This lesson teaches how to classify triangles using the Pythagorean Theorem. It covers identifying right, acute, and obtuse triangles based on their angles. The Pythagorean Theorem is explained, focusing on finding the hypotenuse and using formulas to classify triangles. Examples demonstrate how to apply these concepts to determine triangle types.

What are the characteristics of a right triangle?

How can you identify an acute triangle?

Explain the Pythagorean Theorem and its application.

What does it indicate if the sum of the squares of the legs is less than the square of the hypotenuse?

How do you determine if a triangle is obtuse using the Pythagorean Theorem?
