A cargo plane left London and flew toward the airshow at an average speed of 360 mph. An Air Force plane left sometime later, flying in the
same direction at an average speed of 450 mph. After flying for eight
hours, the Air Force plane caught up with the cargo plane. How long had
the cargo plane been flying for?

What is the point-slope form of the equation for the line with a slope of -2 that passes through (1,4)?

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.

How does reflecting or rotating a figure change the interior angles of the figure?
