Question

what are the two 45 degree angles called?example.. vertical, alternate interior, ect...I know the two middle are the vertical

Answer 1

Consider that angles D and C are alternate interior angles.

Similarly, angles A and E are alternate interior angles.

And since the alternate interior angles made by a transversal over two parallel lines are always equal, it follows that,

`\begin{gathered} \angle D=\angle C \\ \angle A=\angle E \end{gathered}`

But there is no direct relation between the angles E and C.
