Question

The sides of a triangle are 14, 11, and 19. Use the Pythagorean Theorem to determine if the triangle is right, acute, or obtuse.

Answer 1

Pythagorean's theorem is a²+b²=c² with c being the longest sides. If it is true then it is a right triangle.

14^2+11^2=19^2

196+121=361

This is true so the triangle is a right triangle
