Grade 8 Pythagorean Theorem relates the legs a and b of a right triangle to the hypotenuse c by a² + b² = c². Students find a missing side, use the converse to test for a right triangle, and compute distance on the coordinate plane. The hypotenuse is the side opposite the right angle, always the longest.

What you practice

These are the Grade 8 Pythagorean Theorem skills this quiz is built around.

Find a missing leg or hypotenuse in a right triangle using a² + b² = c².
Use the converse to decide whether three side lengths form a right triangle.
Compute the distance between two lattice points by treating the segment as a hypotenuse.

A useful tip

Add the squares of the two legs to get the square of the hypotenuse. Adding the legs first and then squaring treats the theorem like a perimeter formula.
