Identify the angles given in the figure. #### Solution

The angles marked in the figure are on opposite sides of the transversal and in the interior side of the parallel lines and are hence called interior alternate angles.

Assume that $$\displaystyle AB\parallel CD$$ and EF is transversal.

- AInterior alternate angles
- BAdjacent angles
- CCorresponding angles
- DExterior Alternate angles
