Question

A 250-foot length of fence is placed around a three-sided animal pen. Two of the sides of the pen are 100 feet long each. Does the fence form a right triangle

Answer 1

No, it does not form a right triangle.

Explanation:

A + B + C = 250

100^2 + 50^2 doesn't equal 100^2

Neither does 100^2 + 100^2 equal 50^2

The sides are 100, 100, and 50 but these do not make a right triangle
