Question

section 7: transformations & symmetry

1. what type of transformation slides a shape without rotating it?
2. what type of transformation flips a shape over a line?
3. what type of transformation turns a shape around a fixed point?
4. a square is rotated 90° around its center — what type of symmetry does it have?
5. true or false: a circle has only one line of symmetry.

Explanation:

• Question 46: A translation (or slide) moves a shape without rotation.
• Question 47: A reflection flips a shape over a line.
• Question 48: A rotation turns a shape around a fixed point.
• Question 49: When a square is rotated \(90^{\circ}\) around its center and maps onto itself, it has rotational symmetry.
• Question 50: A circle has infinitely many lines of symmetry (any diameter is a line of symmetry), so the statement is false.

Answer:

1. Translation
2. Reflection
3. Rotation
4. Rotational symmetry
5. False
