    One 45º angle and no congruent sides Two 90º angles and two congruent sides Two 45º angles and two congruent sides One 90º and three congruent sides These are the options ^^^^

    Look at choice A. "no congruent sides". That cannot be. There are 2 here. Choice B: two 90 deg angles. 90 + 90 = 180. Since the measures of all angles in any triangle add up to 180, if only two angles add to 180, you have 0 deg left for the third angle. That can't be. Keep on going through each choice and see if it makes sense or not.
