Cotangent
Midpoints and congruent segments
Congruent segments: Segments are congruent if they have the same measure.
If M is the midpoint of , then:
If Z is the midpoint, find and
3y-1=6y-4 -1+4=6y-3y 3=3y y=1
Then = 3(1)-1=3-1=2, =2 units.
= 3y-1+6y-4 = 9y-5 = 9(1)-5 = 9-5 = 4, =4 units.
If =20, C is the midpoint of , and D is the midpoint of , find
