Answer:
It would be a right triangle
Step-by-step explanation:
A triangle must always have 3 angles that add up to 180°.
So if two angles are 45°, then the last angle has to add along with the 45° angles to equal 180°.
If you multiply 45 × 2 (since there are two angles that are 45°), you get 90, which is half of 180.
Also a 90° angle is a right angle, which would help you out with remembering.
I'm sorry if this doesn't make sense, but I hope I helped out
