Chad GagneI am Chad and I am in the eighth grade and I am

thirteen. My favorite subject is Social Studies. But, I am beginning to appreciate math a little more than I did. In January of 2008 I started playing the bass and sense then music has become my passion. I own four basses and two guitars. I also play Tuba in our school band. We recently had our Christmas concert and it was a blast. Me and a flute player named Sarah had

the opportunity to play a song with the advanced band because we had worked hard for it and earned it. When I grow up I hope to do any profession that

has to do with music, whether it is building guitars or playing music I hope to do something with music. This

is all about me for the moment.

Amber Reeves:

I’m 13 years old. My favorite subject is Math and I am in the eighth grade. I was born on August 14 of 1996 in Jackson, Georgia. I am very close to my family and

all my friends. Soon I plan on learning how to play guitar cause I have always loved that instrument. I used to play violin and piano, but I stop cause I lost interest in

both instruments. In the future I would like to be a veterinarian because I absolutely love animals.

Polygons in the Real World

Polygons are everywhere. Every shape with three or more outside lines make these up. So, naturally, this includes buildings, traffic signs, automobiles, chairs, desks, ect. For example, a piece of regular lined paper for school is a rectangle, a quadrilateral,

and overall, a polygon. A stop sign is an octagon, a shape with eight sides and angles; hence it is also a polygon. There are many polygons in the world, and even if

we don’t realize it, we see and use them every day.

Triangles

• A triangle is a polygon which has three sides. Its three interior angles add up to 180°.

Triangles are usually described by reference to their sides or angles. (or both)

• There are three types of triangles. (Scalene, Equilateral, Isosceles triangles.)

• A scalene triangle has all its sides of different lengths. All of its angles must also be of

different sides.

• An equilateral triangle has three congruent sides and three congruent angles.

• An isosceles triangle has at least two congruent angles and two congruent sides.

Quadrilaterals

A quadrilateral is a shape with four sides and angles. Different types of quadrilaterals are

called different things. For example, there are squares, which have four right angles and four

equal sides. In the quadrilateral family are the following:

parallelograms,

rectangles,

rhombuses,

squares,

and trapezoids.

Continue to the following slides for more.

Rhombus

A rhombus is often seen as a diamond, often with two acute angles and two obtuse angles. Like all four sided quadrilaterals, the angles add up to 360 degrees.
