How many lines of symmetry does a SQUARE have?
- 4
- 2
- 1
- 0
Answer: 4. Square: 2 diagonals + horizontal + vertical = 4 lines of symmetry.
ProCompare and infer.
What type of angle is exactly 90°?
- Acute
- Obtuse
- Reflex
- Right
Answer: Right. A right angle is exactly 90°. Acute angles are less than 90°; obtuse are between 90° and 180°.
GuruMulti-step reasoning.
Why do parallel lines never meet?
- Because they are always the same distance apart — that distance never changes.
- Because they are straight.
- Because they were drawn that way.
- Because angles are equal.
Answer: Because they are always the same distance apart — that distance never changes.. Parallel = equidistant. Equal distance means they never converge.
