Learning to determine the number of sides of a regular polygon given one interior angle

The video tutorial explains how to determine the number of sides of a polygon using its interior angles. It introduces the concept of interior angles in polygons, specifically triangles and quadrilaterals, and provides formulas to calculate the sum of interior angles. The tutorial then demonstrates solving an equation to find the number of sides of a polygon, using a hexagon as an example. The process involves applying the distributive property and solving for the variable representing the number of sides.

What is the sum of the interior angles of a triangle?

• 180 degrees

• 120 degrees

• 90 degrees

• 360 degrees

Which formula is used to find the sum of interior angles of a polygon?

• N / 2 * 180

• N + 2 * 180

• N * 180

• N - 2 * 180

What is the sum of the exterior angles of any polygon?

• 180 degrees

• 360 degrees

• 540 degrees

• 720 degrees

If one interior angle of a regular polygon is 120 degrees, how many sides does the polygon have?

• 8

• 4

• 6

• 5

What is the name of a polygon with six sides?

• Octagon

• Heptagon

• Hexagon
