If it is a right triangle and has one 45 degree angle, then it must have two 45 degree angles. Think about it: The sum of the angle in any triangle is 180 -- 180 minus 90 is 90 and 90 minus 45 is 45. Any triangle with two equal angles is an isosceles triangle and the two sides opposite the equal angles have to be of equal measure.
