Question

After locating the incenter I and finding the inradius IP, what is the final step to complete the in-circle?

Options

• Draw a circle with center at vertex A

• Draw a circle with center I and radius IP

• Draw a line parallel to BC

• Connect I to all three vertices

Answer 1

Draw a circle with center I and radius IP

Explanation:

With I as the center and IP (inradius) as the radius, draw the circle. This circle will touch all three sides of the triangle, completing the in-circle construction.
