Question

Isosceles triangle: hypotenuse is 20, what are the side lengths?

Answer 1

Answer:
`10√(2)`

Explanation:

Angles in an isosceles right triangle are: 90, 45, 45.

The ratio of the sides are:
`1:1:√(2)`

Side of 90° = 20

Side of 45° =
`(20)/(√(2) )`

`(20)/(√(2) ) =`
`(20√(2) )/(√(2) ^(2) ) = (20√(2) )/(2) = 10√(2)`
