Answer: Yes, it is a right triangle.
Explanation:
We can use the Pythagorean theorem to determine if this is a right triangle. a and b are the legs (shorter sides) while c is the hypotenuse (longest side).
Given:
a² + b² = c²
Substitute:
(10)² + (24)² = (26)²
Square:
100 + 576 = 676
Add:
676 = 676 ✓
Since 676 = 676 is a true statement, this is a right triangle.
