Question

which type of transformation is shown?
the transformation is a reflection, a type of rigid transformation.
how do the angle measures and side lengths compare?
the angle measures of rectangle qrst are dropdown: greater than, equal to, less than the angles measures of rectangle qrst.
the side lengths of rectangle qrst are dropdown the side lengths of rectangle qrst.
(image shows two rectangles, qrst and qrst, with congruent side markings and right angles.)

Explanation:

Rigid transformations (like reflection) preserve the shape and size of a figure. In a rectangle, all angles are right angles (90°), and side lengths are preserved under reflection. So angle measures and side lengths of the original rectangle (QRST) and the transformed one (Q'R'S'T') should be equal.

Answer:

The angle measures of rectangle QRST are equal to the angle measures of rectangle Q'R'S'T'.
The side lengths of rectangle QRST are equal to the side lengths of rectangle Q'R'S'T'.
