Altitude to the Hypotenuse Theorem - Tomorrow we will use this theorem to prove the Pythagorean Theorem!
2
Altitude to Hypotenuse Theorem: --the alt to hypotenuse forms two smaller right triangles that will be similar to the original
3
Altitude to Hypotenuse Theorem:
4
Altitude to Hypotenuse Theorem: --let’s color the smallest triangle, blue
5
Altitude to Hypotenuse Theorem:
6
Altitude to Hypotenuse Theorem: -- next color the middle triangle red
7
Altitude to Hypotenuse Theorem:
8
Altitude to Hypotenuse Theorem: --now let’s move & rotate the two small triangles to study all three at the same time in the same orientation

Altitude to Hypotenuse Theorem x y c h b a y h b
29
Altitude to Hypotenuse Theorem: either leg of the large triangle is the geom mean of x y h b a the entire hypotenuse and the segment of the hyp adjacent to that leg.

Altitude to Hypotenuse Theorem x h a y h b
31
Altitude to Hypotenuse Theorem: x y c h b a x h a y h b
32
Altitude to Hypotenuse Theorem: --the alt to the hypotenuse is the geometric mean of the two segments of the hypotenuse. x y c h b a
33
Altitude to Hypotenuse Theorem: 1. Alt to hyp forms 3 ~ rt triangles 2.either leg of the large triangle is the geom mean of the entire hyp and the segment of the hyp adjacent to that leg. and x y c h b a 3.the alt to the hyp is the geom mean of the two segments of the hypotenuse.
