Best Answer

There are 180 degrees total in a triangle. A right angle is 90 degrees, so two would already reach 180. (90+90=180) You need three angles to make a triangle, so if there are already 180 degrees, you can't have a third angle.

Can a triangle with a right angle in it have another right angle in it?

No, if there was more than one right angle, it would be physically impossible for the shape to be a triangle. It would have to be a square or rectangle.
