Geometric means Theorem
The size of the altitude drawn from the vertex that the best angle of the best triangle to its hypotenuse is the geometric mean in between the procedures of the two segments the the hypotenuse.
You are watching: What is the length of the altitude drawn to the hypotenuse
This theorem allows you to uncover the size of a segment of the hypotenuse given the length of the altitude and also the length of the other segment of the hypotenuse. Girlfriend can also use this to organize to uncover the length of the altitude given the length of the segments of the hypotenuse.
Find the altutude.
Start through substituting in the well-known values.
Answer: 4, h

h2 = (4) ( ___ )
h2 = ___
Take the square root of each side and simplify.
h = ___
