#### Answer

The property of corresponding angles formed when the parallel lines are intersected by a traversal. When two parallel lines are intersected by a transversal, corresponding angles have the same measures.

#### Work Step by Step

In the given figure, there is a window which contains frames with parallel lines. The snow was collected in the corners that describes the property of corresponding angles of the parallel lines intersected by the traversal.
If there are two parallel lines, the angles formed in the same corners or one angle is interior and one angle is exterior that is on the same side of the traversal are called corresponding angles.
In the picture, the snow is gathered in such a way that corresponding angles are formed on the same side of traversal.
Hence, the property of corresponding angles formed when the parallel lines are intersected by a traversal. And when two parallel lines are intersected by a transversal, corresponding angles have the same measures.
