Arithmetic Mean & Example (3):
|
1. Between x and y --> x + y/2
2. Between 10 and 16
3. 10 + 16/2 = 26/2 = 13
|
|
Geometric Mean & Example(3):
|
1. Between a and b --> a/x = x/b.
2. Between 5 and 5
3. 5/x = x/5; x2 = 25; x = 5

 Label Right Triangle w/ Altitude (6): |
1. a = leg1
2. b = leg2
3. h = altitude (alt)
4. m = segment1 (seg1)
5. n = segment2 (seg2)
6. c = whole hypotenuse (WH)
|
|
Geometric Mean -- Altitude (2):
|
1. seg1/alt = alt/seg2
2. The altitude is the geometric mean between the segments of the hypotenuse.
|
|
Geometric Mean -- leg1 (2):
|
1. seg1/leg1 = leg1/WH
2. Leg1 is the geometric mean between the first segment of the hypotenuse and the whole hypotenuse.
|
|
Geometric Mean -- leg2 (2):
|
1. seg2/leg2 = leg2/WH
2. Leg2 is the geometric mean between the second segment of the hypotenuse and the whole hypotenuse.
