Pythagorean Theorem

Converse of the Pythagorean Theorem

A triangle is obtuse if

A triangle is acute if

a^2 + b^2 = c^2 in a right triangle

If a^2 + b^2 = c^2, then the triangle is a right triangle.

c^2 > a^2 + b^2

c^2 < a^2 + b^2

Pythagorean Theorem

a^2 + b^2 = c^2 in a right triangle

Converse of the Pythagorean Theorem

If a^2 + b^2 = c^2, then the triangle is a right triangle.
