G is the centroid of triangle ABC. What is the length of GF? units

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

Which expression is equivalent to the expression shown?

Aquadrilateral has exactly one pair of parallel sides. which name best describes the figure?
