### PRODUCT DESCRIPTION

Help students discover the properties of eight polygons with this set of interactive fill-in sheets.

Understanding the distinctions between different polygons is an important concept in high school geometry. These handouts are designed to help students see properties and better understand vocabulary terms. The following polygons are included: equilateral triangle, isosceles triangle, scalene triangle, parallelogram, rectangle, rhombus, square, 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 eight sheets can be made into a booklet that students complete as a project.
Centers: 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.

Common Core Standards:

CCSS.Math.Content.HSG.CO.C.10Prove theorems about triangles. Theorems include: measures of interior angles of a triangle sum to 180°; base angles of isosceles triangles are congruent; the segment joining midpoints of two sides of a triangle is parallel to the third side and half the length; the medians of a triangle meet at a point.

CCSS.Math.Content.HSG.CO.C.11Prove theorems about parallelograms. Theorems include: opposite sides are congruent, opposite angles are congruent, the diagonals of a parallelogram bisect each other, and conversely, rectangles are parallelograms with congruent diagonals.

CCSS.Math.Content.HSG.CO.A.3Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself.

CCSS.Math.Content.HSG.GPE.B.4Use coordinates to prove simple geometric theorems algebraically. For example, prove or disprove that a figure defined by four given points in the coordinate plane is a rectangle; prove or disprove that the point (1, √3) lies on the circle centered at the origin and containing the point (0, 2).
