Exploring Angles in Polygons

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

• 180 degrees

• 360 degrees

• 720 degrees

• 90 degrees

How many degrees does each exterior angle of a regular pentagon measure?

• 90 degrees

• 72 degrees

• 60 degrees

• 36 degrees

How can the sum of exterior angles be visually demonstrated?

• Drawing angles on paper

• Calculating with a calculator

• Using a protractor

• Using a geometers sketchpad

If a polygon is equiangular, how do you find the measure of one interior angle?

• 180 minus exterior angle

• None of the above

• Sum of interior angles divided by number of sides

• 360 divided by number of sides

What does it mean if a polygon is described as equiangular?

• It has equal sides

• It has no right angles

• It has equal angles

• It has alternating angles
