This easy-level worksheet has students fix sentence errors, fill in blanks, and write short answers to practice lines and symmetry skills.
It includes 9 questions across 3 sections for focused practice.
Style:
Lines and Symmetry
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A line segment goes on forever in one direction from its endpoint.
Rewrite: A line segment has two endpoints and does not go on forever. A ray goes on forever in one direction from its endpoint.
2. Fix the sentence:
The letter M has 3 lines of symmetry.
Rewrite: The letter M has 1 line of symmetry, running vertically down the middle.
3. Fix the sentence:
Parallel lines always meet at a point far away.
Rewrite: Parallel lines never meet no matter how far they extend.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The letter D has 1 line(s) of symmetry.
2. A ray is named by its endpoint and one other point on the ray.
3. Two lines that are not parallel and do not intersect in a flat surface are called skew lines.
4. The letter O has 2 lines of symmetry.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. How is a line segment different from a line?
A line segment has two endpoints and a fixed length, while a line extends forever in both directions with no endpoints.
2. Name a capital letter that has no lines of symmetry and explain why.
The letter F has no lines of symmetry because you cannot fold it along any line and have both halves match exactly.
Lines and Symmetry
★ Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1) Fix the sentence:
A line segment goes on forever in one direction from its endpoint.
Rewrite: A line segment has two endpoints and does not go on forever. A ray goes on forever in one direction from its endpoint.
2) Fix the sentence:
The letter M has 3 lines of symmetry.
Rewrite: The letter M has 1 line of symmetry, running vertically down the middle.
3) Fix the sentence:
Parallel lines always meet at a point far away.
Rewrite: Parallel lines never meet no matter how far they extend.
★ Part B: Fill in the Blank
Write the missing word or number on each line.
1) The letter D has 1 line(s) of symmetry.
2) A ray is named by its endpoint and one other point on the ray.
3) Two lines that are not parallel and do not intersect in a flat surface are called skew lines.
4) The letter O has 2 lines of symmetry.
★ Part C: Short Answer
Answer each question in one or two complete sentences.
1) How is a line segment different from a line?
