This resource will help students discover the properties of nine polygons.
Understanding the distinctions between different polygons is an important concept in high school
geometry. The following polygons are included: equilateral triangle, isosceles triangle, scalene
triangle, parallelogram, rectangle, rhombus, square, trapezoid, and regular hexagon.
The sheets cover the following concepts:
• Interior angle measures
• Reflection symmetry
• Rotational symmetry
• Angle Bisectors
• Medians
• Diagonals
• Identifying types of polygons on a coordinate grid
Each sheet asks students to draw the polygons, along
with lines of symmetry, angle bisectors, medians,
and/or diagonals. Students decide if statements are
truths or lies. Lastly, students decide if a series of
ordered pairs creates a certain type of polygon.
Ideas for using these sheets:
• Booklet: The nine sheets can be made into a
booklet that students complete as a project.
• Centers or Partners: Students can work together
to complete each polygon in math center format.
• Interactive Notes or Homework: Students
complete sheets to practice vocabulary and to
learn properties.
