Unit 9 Review: Area of Polygons
It's time to show what you know! Individuals first review finding the area of polygons using the formulas from parallelograms to regular polygons. They then brush up on finding the area and circumference of circles, as well as reviewing...
Lesson Planet: Curated OER
Regular Polygons
Make area a regular affair. By dividing a regular polygon into triangles, pupils see how the area formula works. Learners watch several examples of finding the area of various regular polygons before practicing how to find the area of...
Lesson Planet: Curated OER
Unit 5 Review: Quadrilaterals and Polygons
Yes, it will be on the test. Young mathematicians first view an educational video to refresh their memories about material from the unit. They then complete a review worksheet where they find the measures of interior angles of polygons,...
Lesson Planet: Curated OER
Polygon Angles
One's knowledge of angles should measure up to expectations. Scholars watch a video to learn about angles in polygons. They first see how to partition a polygon into triangles to find the sum of the interior angle measures. They then...
Lesson Planet: Curated OER
Finding the Largest Possible Area
If you want a bigger garden, here's a task for you. Given the perimeter of a triangular garden, scholars determine the largest possible area. They then generalize their findings and extend the idea to other polygons.

Interior Angles in Convex Polygons: Lesson
How are angles and sides related? Given several regular convex polygons, the video shows how to calculate the sum of their interior angles. The segment in a playlist on geometry shows how to find the measure of one angle if the polygon...
Lesson Planet: Curated OER
Tessellations: Lesson
Build a pattern by rotating a figure around one of its vertices. A segment of an extensive playlist on basic geometry introduces the concept of tessellations through regular tessellations. The video shows how to create tessellations and...
Lesson Planet: Curated OER
Taking a Spin
It does not divide into 360 evenly, so it cannot work. The resource extends pupils' thinking about rotational symmetry. By asking for a figure with a rotational symmetry of a seemingly impossible angle, the activity requires learners to...

Exterior Angles in Convex Polygons: Lesson
Going around is the same no matter the number of sides. An installment in a geometry playlist explains exterior angles of a convex polygon. The video presents the formula to find the sum of the angles along with the formula for finding...
Lesson Planet: Curated OER
Classifying Polygons: Lesson
For your eyes only: classify the names of polygons. After providing the definition of a polygon, the video introduces the two major classifications of polygons, concave and convex. The segment of a larger playlist on geometry continues...
Lesson Planet: Curated OER
Regular and Irregular Polygons: Polygon States
Colorado would probably object if Wyoming enlarged its borders. Scholars use an interactive map to change the borders of U.S. states to see how angles change. They then answer questions about regular and irregular polygons.
