## Type 1.

r = common ratio = 3/4
h = displacement = 0

r = 3/4, h = 1

r = 3/4, h = 0.5

r = 3/4, h = 0

r = 3/4, h = 4

r = 4/5, h = 0.5

## Type 3.

r1 = 4/7, r2 = 3/4, h = 0

r1 = 4/7, r2 = 3/4, h = 4

r1 = 4/7, r2 = 3/4, h = 3

r1 = 4/7, r2 = 3/4, h = 3.2

r1 = 5/9, r2 = 4/5, h = 0.5

r1 = 4/7, r2 = 3/4, h = 0.8 ~ 3.2
