In the straightedge and compass construction of the equilateral triangle
below, which of the following reasons can you use to prove that AC BC?
Select all that apply.
B
☐ A.
AC and BC are radii of the same circle,
so AC = BC.
AB and AC are radii of the same circle
and AB and DC are radii of the same
B. circle, so AB AC and AB BC
AC and BC are both congruent to AB
so AC BC
AC and BC are radii of the same circle
C. and AB and AC are radii of the same
circle so AC BC and AB = BC.
D.
AB and AC are radii of the same circle
and AB and BC are radii of the same
circle, so AB AC and AB = BC and
AC BC
