Answer each question.
How to solve
Perpendicular lines meet to make a right angle (90°). Parallel lines never meet and stay the same distance apart. A line of symmetry folds a shape into two matching halves, so count every way you could fold it.
Example
Two lines meet at a 90° angle. What are they called?
Answer: perpendicular
Not quite. The answer is
💡 Lines that cross or meet to make a right angle (90°) are called perpendicular lines.
✓ Correct!

Not quite. The answer is
💡 A line of symmetry folds a shape into two halves that match exactly. A rectangle folds into matching halves up and down and side to side. Folding along a diagonal does not match, so it has 2 lines.
✓ Correct!
