Types of angles

o   Acute angle

An acute angle is an angle whose measure is less than 90 degrees.

o   Right Angle

A right angle is an angle whose 90 degrees.

o   Obtuse Angle

An obtuse angle is an angle whose measure is bigger than 90 degrees but less than 180 degrees.

o   Straight Angle

A straight angle is an angle whose measure is bigger than 180 degrees.

o   Reflex Angle

An angle whose measure is bigger than 180 degrees but less than 360 degrees.

o   Adjacent Angle

An adjacent angle is an angle with a common vertex and one common side.

o   Supplementary Angle

Supplementary angles that have two angles whose measure have 180 degrees.

o   Complementary Angle

o   Vertical Angle

Are angles that have a common vertex and whose sides are formed by the same lines.

o   Alternate Interior Angles

Are pairs of interior angles on opposite sides of the transversal.

o   Alternate Exterior Angles

Are pairs of exterior angles on opposite sides of the transversal.

o   Corresponding Angles

Corresponding angles are pairs of angles that are in similar positions.

Divisibility Rules

Divisibility Rules for 2

1.     All even numbers are divisible by 2. E.g., all numbers ending in 0,2,4,6 or 8.

Ex.228

 Divisibility Rules for 3

1.  Add up all the digits in the number.

2.  Find out what the sum is. If the sum is divisible by 3, so is the number.

Ex.3345

Divisibility Rules for 4

1.     The last two digits are divisible by 4.

Ex. 812

Divisibility Rules for 5

1.     Numbers ending in a 5 or a 0 are always divisible by 5.

Ex. 500

Divisibility Rules for 6

1.     The number is divisible by both 2 and 3.

Ex. 114

Divisibility Rules for 9

1.   Add up all the digits in the number.

2.  Find out what the sum is. If the sum is divisible by 9, so is the number.

Ex. 9432

Review 3.1 (Gravity) 
Problem pg. 83 

6. Synthesize

 Presicion measurements of the acceleration due to gravity show that the acceleration is          slightly different in different locations on Earth. Explain why the force of gravity is not            exactly the same everywhere on  Earth's surface. Hint: Think about the details on Earth's      surface.

Answer:
Because of different elevations in Earth.

Review 3.2 (Friction) 
Problem pg.89

6. Synthesize

If you push a book against a wall hard enough, it will not slide down even though gravity is     pulling it. Use what you know about friction and newton's laws of motion to explain                   why the book does not fall.

 Answer:
It doesnt fall because you are pushing it to the wall and thewall is pushing it to you, in result are holding the object up so it doesnt fall.

Review 3.3 (Pressure)
Problem pg. 83

6. Synthesize

During cold winters, ice can form on small lakes and ponds.  Many people skates on thin ice and breaks  through it. Why do rescue workers lie flat on the ice instead of walking upright when reaching out to help rescue skater?

Answer:
Because the weight of the rescuer is divide in a bigger area and preasure is less because of this.

 Geometry
 Is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space.

The basics concepts of geography are:

-Point
 A point has no length, width, or height - it just specifies an exact location. It is zero-dimensional.
Every point needs a name. To name a point, we can use a single capital letter. The following is a diagram of points A, B, and M:

-Line
A line is as wide as a point, infinitely thin, having an infinite number of points, (in a straight row), extending forever in both the directions. Any two lines can intersect at only a single point.

-Line Segments
A line segment, or segment, is a part of a line, which has two endpoints. The endpoints give the line segment a fixed, or finite length.

-Ray
A ray is a line segment that has only one endpoint. A ray is infinite in one direction. That means that it goes on forever in one direction. 

-Midpoints
The midpoint of a segment divides the segment into two segments of equal length. 
The midpoint will be in the middle of A and B. Since M means midpoint.

-Planes
Planes are two-dimensional. A plane has length and width, but no height, and extends infinitely on all sides. Planes are thought of as flat surfaces, like a tabletop. A plane is made up of an infinite amount of lines. Two-dimensional figures are called plane figures.
All the points and lines that lie on the same plane are said to be coplanar.

-Space
Space is the set of all points in the three dimensions - length, width and height. It is made up of an infinite number of planes. Figures in space are called solids.

-Angles
An angle  is a figure by two rays with a common endpoint, and which are not in the same  point.

Tyler and Christina are playing a game in which each player eathjer wins, lose or draw (ties) the winner is awarded 5 points and the loser loses -5 points. If its draw 0 point awarded for the first eight rounds Tyler had tha following results: Lose, win, lose, win, win, lose,win, draw what was christina's  point total for the rounds:

New weeks problem:
National Debt

You have to find the way how much does a child born in 2013 owes at the time of birth.
My opinion is thaty we have to divi de the National Debt that is 25,700,000,000 million, which is around of 10,028,000.

This week's problem:

Why did Kevin Joa falled from the chair when the Teacher  pulled  him?

- I think it is because Kevin's inertia made his body to want to stay in the same place and the it is why he fall down in the same plaxce that he were sitting.

                     My opinion about the video:
                       http://www.youtube.com/watch?v=danYFxGnFxQ

I also agree with Neil, because Isaac Newton was very intelligent and he create and discover a lot of things like: the three laws of motion and gravity. And in your entire live you are going to see this cause is very important in life. He was a man that was very useful for our world, and today he is a man very important in history and that is why all scienfifics,mathematics,phycis and more people value it like a good man that was excellent for our humanity and i am very thankful for that.

"Today is a Great Day to Learn Something New "

The very first week of class fulfill all my expectations, fun, interesting, and full of new knowledge. We started with a new topic called Algebraic Expressions, I love this topic! I did my homework with so much joy, I'm  very proud of myself. I'm happy and ready to accomplish my goals with my great teacher: Mr. Eladio. I know you are reading this that's why i wanted to tell you: you explain very well. 

I want to keep learning, the way I am in this class, it doesnt feel like a math at all! I try my best at home with the homework, and then check it on class! Learning from our mistakes is the best thing we can do. I will practice and give my best effort. 

Sincerely, Soph
