Steps of construction

Question

What step is similar when constructing a circle inscribed in a triangle and a circle circumscribed about a triangle?

A. Construct the angle bisector of each angle in the triangle

B. Construct the perpendicular bisector of each side of the triangle

C. Use the intersection of the bisectors to find the center of the circle

D. Use a compass to locate the intersection of the midpoint of each side

Answer 1

The circle inscribed in.a triangle has its center at the in-center

The circle circumscribed outside a triangle has its center at the circum-center

The in-center is the intersection of all three angle bisectors

The circum-center is the intersection of all three sides' perpendicular bisectors
