Problem 1Difficulty: Mastery
The diagram shows a square with identical semicircles attached outward to all four sides, like a four-petal shape. How many lines of symmetry does it have?
Solution & Explanation:The identical petals and square center match across vertical, horizontal, and both diagonal fold lines.
Problem 2Difficulty: Mastery
The diagram shows a square with a small triangle centered on each side, but the top and bottom triangles are shaded while the left and right triangles are unshaded. Which lines of symmetry remain?
Avertical and horizontal center lines
Bboth diagonal lines only
Chorizontal center line only
Dno lines of symmetry
Solution & Explanation:A vertical fold swaps the unshaded side triangles and leaves the shaded top and bottom in place; a horizontal fold swaps the shaded top and bottom and leaves the side pair in place. Diagonal folds would swap shaded and unshaded triangles.
Problem 3Difficulty: Mastery
The diagram shows a 4 by 4 grid with shaded cells forming both diagonals, like an X. How many lines of symmetry does the design have?
