Questions

How many lines of symmetry does an equilateral triangle have?
1. 1
2. 2
3. 3
4. 4
Show answer
Answer: 3
An equilateral triangle has 3 lines of symmetry, each going from a vertex to the midpoint of the opposite side.
A rectangle that is not a square has 4 lines of symmetry.
Show answer
Answer: False
A non-square rectangle has only 2 lines of symmetry (horizontal and vertical through midpoints). The diagonals are NOT lines of symmetry.
A line that divides a shape into two matching halves is a line of ___.
Show answer
Answer: symmetry
A line of symmetry divides a shape into two halves that are mirror images of each other.
Which shape has the MOST lines of symmetry?
1. Square
2. Equilateral triangle
3. Circle
4. Regular hexagon
Show answer
Answer: Circle
A circle has infinitely many lines of symmetry. Every diameter is a valid line of symmetry.
The letter H has both a vertical and a horizontal line of symmetry.
Show answer
Answer: True
H is symmetric both vertically (left-right) and horizontally (top-bottom), giving it 2 lines of symmetry.
A square has ___ lines of symmetry.
Show answer
Answer: 4
A square has 4 lines: 2 through midpoints of opposite sides, 2 through opposite corners.
Which of these has exactly 1 line of symmetry?
1. Square
2. Circle
3. Isosceles triangle
4. Equilateral triangle
Show answer
Answer: Isosceles triangle
An isosceles triangle has exactly 1 line of symmetry — from the top vertex to the midpoint of the base. An equilateral triangle has 3.
A scalene triangle has at least one line of symmetry.
Show answer
Answer: False
A scalene triangle has no equal sides and no equal angles, so it has no lines of symmetry.
A regular hexagon has ___ lines of symmetry.
Show answer
Answer: 6
A regular hexagon has 6 lines of symmetry: 3 through opposite vertices and 3 through midpoints of opposite sides.
Which letter does NOT have a line of symmetry?
1. A
2. H
3. M
4. F
Show answer
Answer: F
F has no line of symmetry. A, H, and M all have at least one vertical line of symmetry.
