In the diagram below of triangle VWX, Y is a midpoint of VW and Z is a midpoint of W X. IfYZ = 21 – 1, and VX = 106 – 102,
what is the measure of Y Z?

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
