They come in many shapes and sizes!
3
3 measure angles –Acute –Right –Obtuse 3 measure sides –Scalene –Isosceles –Equilateral There are 6 types of triangles.
4
Isosceles Triangle The left and right side are 5 centimeters long. This triangle has at least two equal sides.
5
1. Equilateral Triangle This triangle has all congruent sides. This triangle also has the congruent angles, each being 60º.
6
The bottom line wins for the longest side. This triangle consists of three sides that are all different.
7
Obtuse Triangle It’s the bottom triangle @ 120º. This triangle has one of the three angles larger than 90º.
8
Acute Triangle This triangle has all three angles measuring less than 90º. Remember that every triangle has a sum of 180º for all three angles.
9
The Right Triangle This very special triangle has one angle that is exactly 90º. The other two angles always have a sum of 90º. Everything seems RIGHT about this triangle!
