Question

triangle efg is transformed to create triangle efg. which transformation occurred? options: translation, stretch, rotation, reflection

Explanation:

Step1: Analyze Translation

Translation moves a figure without rotating or reflecting. The triangles don't look shifted without rotation/reflection. So not translation.

Step2: Analyze Stretch

Stretch changes side lengths, but marked sides (congruent marks) suggest lengths same. So not stretch.

Step3: Analyze Rotation

Rotation turns a figure. The orientation change (e.g., right angle position) fits rotation.

Step4: Analyze Reflection

Reflection flips over a line, but the orientation here is more like a turn (rotation) than a flip. So rotation is correct.

Answer:

rotation (the option labeled "rotation")
