Question

what is the first step in constructing a circumscribed circle around triangle xyz? construct the angle bisector of angle y. construct a copy of angle x. construct the perpendicular bisector of segment xy. construct a line parallel to segment yz.

Explanation:

Step1: Recall circum - circle construction

To construct a circumscribed circle around a triangle XYZ, we first need to find the circum - center. The circum - center is the point of intersection of the perpendicular bisectors of the sides of the triangle. So, the first step is to construct the perpendicular bisector of one of the sides of the triangle.
Construct the perpendicular bisector of segment XY.

Answer:

Construct the perpendicular bisector of segment XY.
