On the graph, 2 right angles have the line as the hypotenuse. In this task, you will use these triangles to show that the slope between points E and A is the same slope between A and C Q1: which angles of the triangle measures 90°?

Q2: to show that the other 2 angles measurements in he's triangle are equal, you can use parallel lines cut by a transversal. Which 2 pairs of lines segments formed by triangle slides are parallel and what is the transversal for each pair?
