Answer:
1:1
Explanation:
Im pretty sure its 1:1 because its an isosceles triangle. think of a 45-45-90 triangle as a square cut in half diagonally--the sides of a square are all equal so the ratio of one leg to the other is 1:1
there are two legs and one hypotenuse in a right triangle--the hypotenuse is the longer side, opposite the right angle
