Question

Each triangle in the diagram is a reflection of another triangle across one of the given lines. How can you describe Triangle 2 by using a reflection rule?

I. Rl (Triangle 3)
II. Rm(Triangle 2)
III. Rm (Triangle 1)

A. I only
B. I and III only
C. II and III only
D. I, II, and III
(I put C. but it was wrong, now i'm thinking A.?)

Answer 1

A

Explanation:

Answer 2

Based on the given figure, triangle 2 is the reflection of triangle 3 across line l. Triangle 2 is also the reflection of triangle 1 across diagonal m.

Reflection is the transformation of a figure that shows the flip side of the figure. The reflection is congruent to the reflected image.

My answer is: B. I and III only
