In this lesson, you classified triangles according to side length and angle measure. Terms such as equilateral, isosceles, scalene, acute, obtuse, and right are associated with the classification of triangles. Applying the Pythagorean theorem has been useful in this lesson to help determine the side lengths of right triangles.

 

In the next lesson, quadrilaterals will be examined. Some of the topics in this lesson about triangles will be applied to quadrilaterals.
