Argument a: there is a need for students to understand and be able to construct geometric figures using a compass and straightedge. argument b: there is no need for students to use a compass and straightedge, and all geometric constructions should be done using a drawing program.

What is the value of y? round to the nearest tenth

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.
