During Polygraph: Parabolas, Sarah asked this question: "Does your parabola look like a smile?" (1) Drag the blue points to show what the graph could have looked like if the answer was "yes."

(2) What other word or phrase could we use for "looks like a smile"?

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.
