Quiz on geometric transformations featuring multiple-choice questions with diagrams of shapes on coordinate planes.

Let’s go through each question one by one.

Question 1:

We see two triangles on a grid. One is above the x-axis, and one is below — they look like mirror images across the x-axis.

- Translation? No — that would mean sliding without flipping or turning.
- Rotation? No — rotating would turn it around a point, not flip it over.
- Enlargement? No — size hasn’t changed.
- Reflection? YES — it’s flipped over a line (the x-axis).

✔ So, answer is Reflection → Option B

Question 2:

Blue shape is in top-left quadrant, red shape is in bottom-right. They look like they’ve been turned 180 degrees around the origin.

- Rotation? YES — specifically 180° rotation around the center (origin).
- Reflection? Not really — reflection would flip over a line, but here it’s turned.
- Translation? No — position changed more than just sliding.
- Enlargement? Size looks same.

✔ So, answer is Rotation → Option A

Question 3:

This is a definition question.

“Changes the size of a figure, but not the shape” — that’s exactly what an enlargement (or dilation) does.

- Rotation? Changes orientation, not size.
- Translation? Just moves it.
- Reflection? Flips it.

✔ So, answer is an enlargement → Option B

Question 4:

Red triangle → Blue triangle.

Looking at positions: Red is on right, blue is on left. Same size, same orientation — just moved left and down.

That’s a translation — sliding without turning or flipping.

- Enlargement? No — size same.
- Reflection? No — not mirrored.
- Rotation? No — not turned.

✔ So, answer is Translation → Option C
