Question
10. A triangle has side lengths of 120 mm, 160 mm, and 200 mm. Is the triangle a right triangle? Explain your reasoning.
Answer
120 x 120 = 14400
160 x 160 = 25600
200 x 200 =40000
The triangle is a right triangle because 14400 (120 squared) plus 25600 (160 squared) equals 40000 (200 squared). The Pythagorean Relationship works!
