Francine walks 7 blocks to school each day, Monday through Friday. She walks home every day except tuesdays and thursdays when she stays after school for band practise and her mother picks her up. How many blocks will francine walk in 2 weeks?

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.
