The length of legs of isosceles right triangle is 8.5 cm
Solution:
Given is a isosceles triangle
hypotenuse = 12 cm
In an isosceles right triangle, the legs have equal lengths
Let these sides be each "a" cm
By pythogoras theorem,
![(Hypotenuse)^2 = (leg)^2 + (leg)^2\\\\12^2 = a^2+a^2\\\\2a^2 = 144\\\\a^2 = 72\\\\Take\ square\ root\ on\ both\ sides\\\\a = √(72)\\\\a = 8.49 \approx 8.5](https://img.qammunity.org/2021/formulas/mathematics/middle-school/t8oaqtqwh073xsgnnldb15ssusgyn7cus6.png)
Thus the length of leg of isosceles right triangle is 8.5 cm
