What are the 6 words we use to classify triangles? By sides and by angles.
Acute, right, obtuse, scalene, isosceles, equilateral.

What is perimeter and how can I find it?
The distance around a polygon. Find it by adding all the sides, 2l +2w, or 4s.
100
What is area and how do I find it?
Area is the inside of a polygon and can be found by multiplying length times width.
