Lesson: Symmetry
Regular quadrilaterals have 4 angles and 4 lines of symmetry. Regular pentagons have 5 angles and 5
lines of symmetry. Regular hexagons have 6 angles and 6 lines of symmetry. If this pattern were to
continue, how many lines of symmetry does a regular heptagon have?
A) 7
B) 8
C) 3
D) 2
Standard: 4.G.A.3
Domain: Geometry
Theme: Draw and identify lines and angles, and classify shapes by properties of their lines and angles
Description: Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that
the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of
symmetry.
