Explanation:

Answer 2

The triangles that are right triangles includes

20 √(425) 5

6 8 10

How to find the right triangle measure

The triangle dimensions that defines right triangle are determined using Pythagorean theorem

Let us check for the various sizes

20 √(425) 5

= √(20² + 5²)

= √(425)

This is a right triangle

14 21 10

= √(14² + 10²)

= √(296)

= 17.2

This is not a right triangle

6 8 10

= √(6² + 8²)

= √100

= 10

This is a right triangle
