Question

A triangle is formed with side lengths of 7 inches, 24 inches, and 25 inches. Is the triangle a right triangle?

A
The triangle is a right triangle because 2(7)+2(24)=2(25) .

B
The triangle is a right triangle because 7^2+24^2=25^2 .

C
The triangle is not a right triangle because 25^2−24^2=7^2 .

D
The triangle is not a right triangle because 7^2+^25^2=24^2 .

Answer 1

Explanation:

The traingle in Question B and A are right traingle because..If you use pythagoras theorem in those two questions,the sum of square of smaller two sides will be equal to the square larger side. Therefore they are rt.triangle. In D the case is opposite. As the sum of square of two smaller sides are comparatively more than larger sidei.e. hypotenuse. So it is not rt. triangle. This is your answer.
