Your friend is mistaken; reflecting a figure does not change its angles or size, and therefore the figure remains congruent to the original. Reflection is a rigid transformation that maintains all properties of the figure, including angle measures and side lengths. For example, if you reflect a triangle with angles of 30°, 60°, and 90°, the reflected triangle will still have angles of 30°, 60°, and 90°, thus confirming they are congruent.
Your friend tells you that reflecting a figure will make the figures angles smaller, so it is no longer congruent to the origonal figure. is this true? why or why not? in 3 sentences explain your answer and describe an example the would verify your claim
