The rectangular prism has a volume of, 1/4 cubic meter.
Answer:
111.4
Step-by-step explanation:
The corresponding angles of triangle ABC and its image are congruent
<h3>How to determine the relationship?</h3>
The transformation rule is given as:
A rotation of 180 degrees about the origin
The rotation transformation is a rigid transformation.
This means that it does not alter the side lengths and the angle measure of the shape being rotated
Hence. the corresponding angles of triangle ABC and its image are congruent
