GMAT right angle assumption----Support beams

When you get a problem asking you to solve a triangle problem and the question is on triangles resulting from a support beam do you assume that the angle formed by the base of the support beam is a right angle? I am of the firm belief that you NEVER assume anything with the GMAT. However, I have come across several GMAT practice resources that give you a triangle question and apparently want you to assume that it is obvious that the angle on the base of a support beam is always 90 degrees. Anyone have any thoughts?

You are correct not to assume anything in word problems. It just indicates that the resources are not being thorough.
