Question

True or false:
FGH is a right triangle​

Answer 1

False

Explanation:

Suppose |FG| is hypotenuse

the sum of square length of side legs must be equal to square of hypotenuse

(√63)^2 + 6^2 = 10^2

63 + 36 = 100

99 is not equal to 100 therefore the given triangle is not a right triangle.
