Question

Scott is constructing a circle circumscribing triangle ABC. Which step will he use to locate the center C of the circle?
He will construct the bisector of angles A and B and label the point of intersection of the two angle bisectors as C.
He will construct the perpendicular bisector of sides AB and BC and label the point of intersection of the perpendicular bisectors as C.
He will construct a line from vertex A to the midpoint of side BC and a line from vertex B to the midpoint of side AC and label the point of intersection of the two lines as C. x
He will construct a line

Answer 1

I think it's between the first two.

Answer 2

The circumcentre of a triangle is the point of intersection of the right bisectors of each side, so the second answer is right.

Answer 3

Thank you!
