Question

if \\(\overline{vy}\\) is not parallel to \\(\overline{wx}\\), what is \\(m\angle v\\)?
\\(m\angle v = \square^\circ\\)

Explanation:

Step1: Recall the property of a parallelogram

In a parallelogram, adjacent angles are supplementary (sum to \(180^{\circ}\)). But since \( \overline{VY}\) is not parallel to \( \overline{WX}\), we consider the property of a trapezoid. Wait, no, looking at the markings: two pairs of adjacent sides are equal. Wait, no, actually, if two pairs of adjacent sides are equal (marked with one tick and one arrow), but no, wait, in a quadrilateral, if two pairs of adjacent sides are equal (a kite - like shape? No, wait, no. Wait, actually, in a quadrilateral, the sum of interior angles is \(360^{\circ}\). But since two sides are equal (marked with one tick) and two sides are equal (marked with one arrow). Wait, no, actually, if \( \overline{VY}\) is not parallel to \( \overline{WX}\), but we have a quadrilateral where \(VY = WX\) (marked with one tick) and \(VW=YX\) (marked with one arrow). So it's a parallelogram? No, because \( \overline{VY}\) is not parallel to \( \overline{WX}\). Wait, no, wait, in a parallelogram, opposite sides are parallel. But the problem says \( \overline{VY}\) is not parallel to \( \overline{WX}\). Wait, no, actually, in a parallelogram \(VY\parallel WX\) and \(VW\parallel YX\). But since \( \overline{VY}\) is not parallel to \( \overline{WX}\), but we have \(VY = WX\) and \(VW = YX\). Wait, no, in a parallelogram opposite sides are equal and parallel. But if only opposite sides are equal ( \(VY = WX\) and \(VW = YX\)), then it is a parallelogram (by SSS - congruence of triangles formed by a diagonal). But the problem says \( \overline{VY}\) is not parallel to \( \overline{WX}\). Wait, no, contradiction. Wait, no, actually, in Euclidean geometry, if in a quadrilateral \(VY = WX\) and \(VW = YX\), then \( \angle V+\angle X = 180^{\circ}\) (because the sum of interior angles of a quadrilateral is \(360^{\circ}\), and if \( \angle V=\angle Y\) and \( \angle W=\angle X\) (if it were a parallelogram, but no). Wait, no, wait, actually, if \(VY = WX\) and \(VW = YX\), then triangles \(VYW\) and \(WXY\) are congruent (by SSS: \(VY = WX\), \(VW = YX\), \(WY = WY\)). So \( \angle V=\angle X\) (corresponding parts of congruent triangles). But \( \angle X = 103^{\circ}\), so \(m\angle V=77^{\circ}\) (because \( \angle V+\angle X = 180^{\circ}\) in a parallelogram, but no, wait, no, in a quadrilateral with \(VY = WX\) and \(VW = YX\), the sum of \( \angle V+\angle X\) is \(180^{\circ}\) (since the quadrilateral can be thought of as two congruent triangles. Let's use the property of the sum of interior angles of a quadrilateral \(S=(4 - 2)\times180^{\circ}=360^{\circ}\). Let \(m\angle V=x\), \(m\angle X = 103^{\circ}\), and since \( \angle V=\angle Y\) and \( \angle W=\angle X\) (from triangle congruence: \(\triangle VYW\cong\triangle WXY\)), then \(x + 103^{\circ}+x + 103^{\circ}=360^{\circ}\).
