Back

An isosceles triangle has at least two sides that are equal in length and the angles opposite those sides are equal.

Front

How do you find the measure of an angle in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees. You can find the measure of an unknown angle by subtracting the sum of the known angles from 180 degrees.

What is the smallest angle in a triangle?

Back

The smallest angle in a triangle is the angle opposite the shortest side.

Front

How do you order sides of a triangle from least to greatest?
