Classifying Triangles Using The Pythagorean Theorem Geometry Activity

In this maze, geometry students use the Pythagorean Theorem to classify triangles as acute, right, or obtuse. The focus is on comparing side lengths and applying the converse of the Pythagorean Theorem.

How it works

Students are given 11 sets of triangle side lengths. For each one they determine the triangle type based on the relationship between the squares of the side lengths.

Correct answers guide their path through the maze, so the self-checking is built in. A wrong classification sends them off the path, which pushes them to be accurate and to think it through again.
