Alternate Exterior Angles: Lesson
2 mins 9th - 12th CCSS: Adaptable
Use an alternate approach to parallel lines. A resource in a comprehensive playlist on basic geometry develops the concept of alternate exterior angles and parallel lines. The presentation demonstrates how to identify alternate exterior...
What are Interior and Exterior Angles of a Polygon?
5 mins 6th - 10th
Break down interior and exterior angles with this video. Using a pentagon, a teacher demonstrates how to find the interior and exterior angles of a polygon. She goes on to explain a few of the properties of these angles, writing down all...
Understand the Relationship Between Exterior Angles
3 mins 7th - 9th CCSS: Designed
Beginning with a review on angles, the lesson describes how exterior angles are related to interior angles. Watch how the rest of the angles can be determined based on one interior and one exterior angle given. The video finishes with...
Interior Angles, Exterior Angles, and Diagonals of Polygons
8th - 11th CCSS: Adaptable
How does the number of sides of a polygon affect the angle measures? Learners recognize a pattern in finding the total measure of interior and exterior angles and the number of diagonals. They use the patterns to calculate the number of...
How Do You Find the Measures of Exterior Angles of a Polygon if You Know the Interior Angles?
5 mins 6th - 10th
What are the exterior angles of a polygon? Polygons have exterior angles? How? Oh, extend all the lines, and find the value of each of the supplementary angles. No problem as long as one knows what supplementary angles means. Not sure?...
How Do You Find Measures of Missing Exterior Angles?
3 mins 6th - 10th
The sum of the exterior angles of any polygon is always 360 degrees. So knowing this, finding missing exterior angles can be done as long as there is only one variable in the equation. All that needs to be done is to add all the known...
Relationship between Exterior and Remote Interior Angles in a Triangle
In this triangle activity set, 9th graders find the relationship between the exterior and remote interior angles in triangles. They determine the formula, and apply it in 15 problems. They use a compass as needed to measure angles.
Sum of Exterior Angles of Polygons
