What exactly is a triangle?

• A triangle is a type of polygon with three sides
  and three angles.
• All of the sides are made with straight lines.
• There are three types of triangles when
  classified by the length of the sides.
• 1. Equilateral
• 2. Scalene
• 3. Isosceles

3
The first type of triangle is called an
equilateral triangle.
An equilateral triangle has three sides that are
congruent, meaning all of the sides are the same
length.
4
The second type of triangle is called a scalene
triangle.

• Scalene triangles do not have any congruent
  sides, meaning none of the sides are the same
  length.

5
The third type of triangle is called an
isosceles triangle.

• Isosceles triangles only have two congruent
  sides, meaning only two sides are the same
  length.

6
Lets see what you know!

• What type of triangle only has two congruent
  sides?
• Isosceles
• Equilateral
• Scalene

7
You are right!

• Good job!

Oops! Lets go through our triangles and try again.

About me
I am a senior at WMU and ready to move onward. I
love animals, being outside, and spending time
with my friends and family. I also love to
teach, especially math! I plan on joining the
urban program, which means I will be starting my
pre-internship at Edison Elementary in the
Spring. After I graduate, I plan on moving out
of Michigan.
