Hello! Right Triangle Altitude Theorem Part a: The measure of the altitude drawn from the vertex of the right angle of a right triangle to its hypotenuse is the geometric mean between the measures of the two segments of the hypotenuse.

ik what it is how do i find it tho

OpenStudy (harleyquinn98):

the length of it

OpenStudy (flower-girl):

Recall the geometric mean between two positive numbers a,b is the number x such that \[x=\sqrt{a*b}\]

OpenStudy (flower-girl):

First consider the two triangles formed by the altitude:

OpenStudy (harleyquinn98):

yup both the bases on each triangle is 6 and the area of the big triangle is 24 units i need to find the length of the altitude.

OpenStudy (flower-girl):

\[AD=\sqrt{CD*DB}\]
