The correct answer is: Opposite angles of a parallelogram are congruent.

In a parallelogram, the opposite angles are always congruent. The opposite angles are the angles diagonal across from each other.

You can tell by the order of ABCD that A and C are opposite. B and D are also opposite of each other and congruent.

The figure is reflected across line m and the reflected across line n. What type of transformation is the result?
slega [8]

It's a translation.

A reflection across a line is like flipping that object like a pancake over the line.  It gets turned upside-down.

When you flip the pancake again, now across a parallel line, it gets turned right-side up again, just in a new location.
