Question

An isosceles right triangle has leg lengths of 4 centimeters. What is the length of the altitude drawn from the right angle to the hypotenuse?

2 cm
2 StartRoot 2 EndRoot cm
4 cm
4 StartRoot 2 EndRoot cm

Answer 1

B

Explanation:

Edge

Answer 2

Explanation:

(4sqrt2)/4 = 4/(projection)

sqrt2 = 4/(projection)

projection = 2sqrt2

So by the Pythagorean theorem, the altitude is also 2sqrt2.
