Lines of Symmetry
Find every line of symmetry in polygons and letters.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 91
- A line of symmetry folds a figure into two matching halves. The letter T has one: straight down the middle.
- The letter H has two: up and down, and side to side.
- Some figures have none, like the letter F. A square has 4, and a regular hexagon has 6!
Georgia's K-12 Mathematics Standards:
- 4.GSR.8.1 — Explore, investigate, and draw points, lines, line segments, rays, angles (right, acute, obtuse), perpendicular lines, parallel lines, and lines of symmetry. Identify these in two-dimensional figures.
