This medium-level worksheet has students fill in blanks, and match items from two columns to practice lines and symmetry skills.
It includes 10 questions across 2 sections for focused practice.
Style:
Lines and Symmetry
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Two intersecting lines that do not form right angles are called oblique lines.
2. A regular triangle has 3 line(s) of symmetry.
3. The symbol → is used to show a ray in math notation.
4. An isosceles trapezoid has 1 line(s) of symmetry.
5. The capital letter I has 2 line(s) of symmetry.
6. A rectangle has 2 pair(s) of parallel sides.
7. Two rays that share the same endpoint form an angle.
8. A regular decagon has 10 lines of symmetry.
9. If you fold a shape along a line of symmetry, the two halves overlap perfectly.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Regular pentagon
→ 5 lines of symmetry
6 lines of symmetry
Isosceles triangle
→ 1 line of symmetry
0 lines of symmetry
Regular hexagon
→ 6 lines of symmetry
1 line of symmetry
Right scalene triangle
→ 0 lines of symmetry
5 lines of symmetry
