The sum of the angles of a triangle must be 180 degrees. If two angles are 90 degrees, the third angle must be zero. You need three non-zero angles to make a triangle. Therefore a triangle cannot have two right angles. QED

algebra
aren't the corners 90 degrees, bisected by the diagonols? And then in any triangle, the sum of angles 180? So that makes the central angles 90, or perpendicular.

math
The sum of the angles of a triangle is 180 degrees. Yours is an isosceles triangle, and the vertical angle is four times the size of a base angle - so you've got two base angles, plus four more base angles in the vertical angle. That's six base angles in total, which ...
