A kite has to one one set of opposite, equal angles.

A quadrilateral and trapezoid do not have to have any equal angles. 

A square has angles that all measure 

A kite, parallelogram, and rhombus do not have to have angles that measure 

A rectangle has angles that all measure 

A kite, parallelogram, and rhombus do not have to have angles that measure 

A square has to have  equal sides. 

A rectangle and parallelogram have opposite, equal side lengths. 

A kite has two pairs of adjacent sides that are equal. 

A parallelogram and a rhombus have two sets of opposite, equal angles. 

A kite only has one set of opposite, equal angles and a quadrilateral does not have to have any equal angles. 

First, let's define the possible transformations. 

Rotation: A rotation means turning an image, shape, line, etc. around a central point.

Translation: A translation means moving or sliding an image, shape, line, etc. over a plane.

Reflection: A reflection mean flipping an image, shape, line, etc. over a central line. 

In the images from the question, notice that the black angle rotates  counterclockwise, or left around the y-axis. The vertical, base, line of the angle goes from being vertical to horizontal; thus the transformation is a rotation. 

The transformation can't be a reflection over the x-axis because the orange angle didn't flip over the x-axis. 

The transformation can't be a translation because the angle changes direction, which does not happened when you simply move or slide an angle or image.

Reflection: A reflection mean flipping an image, shape, line, etc. over a central line. 

In the images from the question, notice that the black angle rotates  clockwise, or right around the x-axis. The vertical, base, line of the angle goes from being vertical to horizontal; thus the transformation is a rotation. 

The transformation can't be a reflection over the y-axis because the orange angle didn't flip over the y-axis.

In the images from the question, the line was not rotated  because that rotation would have caused the vertical, base, line of the angle to go from being horizontal to vertical, but the line is still horizontal. The line was not moved down, as the translation is described in the answer choice, because you can tell the angle has been flipped, the straight, base line of the angle is now the top line of the angle; thus, the correct answer is a reflection over the x-axis.
