Question

understand types of transformations
click on the pair of triangles that show that one is a reflection of the other.
(there are images of triangle pairs here, omitted as per instruction)

Explanation:

Step1: Recall Reflection Definition

A reflection is a transformation that flips a figure over a line, creating a mirror image. The two figures should be congruent and mirror each other across an axis.

Step2: Analyze Each Pair

• First pair: Triangles are rotated, not reflected.
• Second pair: The two triangles are mirror images (flipped over a vertical line), showing reflection.
• Third pair: Triangles are translated (slid), not reflected.
• Fourth pair: Triangles are rotated, not reflected.

Answer:

The pair of triangles in the second position (the middle - left and middle - right triangles among the four pairs)
