Answer:

The answer to your question is below

Step-by-step explanation:

Process

To answer if they are right triangles or not use the Pythagorean theorem which states that the square of the hypotenuse equals the sum of the square of the legs.

a) 25² = 20² + 7²

625 = 400 + 49

625 ≠ 449 It is not a right triangle

b) 26² = 24² + 10²

676 = 576 + 100

676 = 676 it is a right triangle

c) 13² = 8² + (√10)²

169 = 64 + 10

169 ≠ 74 it is not a right triangle

d) 52² = 48² + 20²

2704 = 2304 + 400

2704 = 2704 it is a right triangle
