Question

triangles klm and klm are congruent. which transformation to triangle klm was used to create triangle klm? a. reflection b. translation c. rotation 90° clockwise d. rotation 90° counterclockwise

Explanation:

Step1: Recall transformation definitions

• Reflection: Flips a figure over a line.
• Translation: Slides a figure without rotation or reflection.
• Rotation: Turns a figure around a point.

Step2: Analyze the given triangles

The dashed line is like a mirror. Triangle \(K'L'M'\) is a mirror - image of \(KLM\). This is characteristic of a reflection. A translation would just move the triangle without flipping. A \(90^{\circ}\) rotation (clockwise or counter - clockwise) would change the orientation in a rotational way (not a mirror - like flip).

Answer:

A. reflection
