Question

Is side length 10, 20, and 30 a right triangle

Answer 1

No, these numbers are not a right triangle.

Explanation:

The legs are the two smallest number and the hypotenuse (c) is the biggest number.

a² + b² = c²

10² + 20² = 30²

100 + 400 = 900

500 = 900 Not true . These numbers are not a right triangle.
