Point y is the circumcenter of triangle d e f. lines are drawn from the points of the triangles to point y. lines are drawn from point y to the sides of the triangle to form right angles and line segments y l, y m, and y n. the line segments cut the sides of the triangles into 2 equal parts. which statement is true about point y?
a) point y is the center of the circle that passes through points d, f, and n.
b) point y is the center of the circle that passes through points m, n, and e.
c) point y is the center of the circle that passes through points l, m, and n.
d) point y is the center of the circle that passes through points d, e, and f.
