Question 38 • Geometry
The triangle inequality says the sum of any two side lengths of a triangle must be greater than the third side. Thus EF + FG > EG, so statement B is true, and EG + FG > EF, so statement C is true. Also, EG − FG < EF follows by rearranging EG < EF + FG, making D true. The other statements contradict the triangle inequality: a difference of two sides cannot be greater than the third, and a sum of two sides cannot be less than the third.
