Line segment ab has 1 length of 24 units. point c is the midpoint of ab. point d is the midpoint of ac. what is the length of cd?
a. 6 units
b. 12 units
c. 24 units
d. 48 units

a 6 units, because ab is 24units, c is halfway making like ac 12 units, d is the midpoint for ac, half of ac or 12 units is 6 units, so that would be the answer if it asked for ad or cd

Angle A and Angle D are congruent because angles of an equilateral triangle are congruent.

Side AD is equal to side AD because of the reflexive property

Side AC is congruent to side DB because components of sides are congruent

Therefore, Triangle ACD is congruent to Triangle DBA
