#### 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...

Lesson Planet: Curated OER

#### 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.

Lesson Planet: Curated OER
