Answer:
Ratio of sides length of triangle is 1 : 1 : √2.
Step-by-step explanation:
Given : 45-45-90 right triangle.
To find : what is the ratio of the length of one leg to the length of the other leg.
Solution : We have given that 45-45-90 triangle .
By the 45-45-90 triangle rule perpendicular sides are equal in length and hypotenuse is √2 times of either perpendicular side.
Therefore , ratio of sides length of triangle is 1 : 1 : √2.
