Question

xy ≅ yz.
which term describes wy?
median angle bisector
perpendicular bisector none of these

Explanation:

A median of a triangle is a line segment joining a vertex to the mid - point of the opposite side. Here, we are only given that \( \overline{XY}\cong\overline{YZ}\) (i.e., \(Y\) is the mid - point of \(XZ\)), but there is no information about \(WY\) being a line from a vertex (\(W\)) to the mid - point of the opposite side (\(XZ\)) in the sense of a median (because we don't know if \(WY\) connects \(W\) to \(Y\) in the context of triangle \(WXZ\)'s median). Also, there is no indication that \(WY\) bisects an angle of the triangle (no angle - equal markings) or that \(WY\) is perpendicular to \(XZ\) (no right - angle markings).

Answer:

none of these
