Understanding Angles in Polygons

What is the relationship between interior and exterior angles in a polygon?

• They are complementary.

• They add up to 90°.

• They are equal.

• They form a straight line.

How do you calculate the sum of interior angles in a polygon with 'n' sides?

• n * 180°

• (n - 2) * 180°

• (n + 2) * 180°

• n * 360°

If a regular pentagon has a total interior angle sum of 540°, what is the measure of each interior angle?

• 120°

• 135°

• 108°

• 90°

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

• 540°

• 180°

• 360°

• 720°

How can you determine the number of sides in a regular polygon if you know the measure of one exterior angle?

• Subtract the exterior angle from 180°

• Add the exterior angle to 180°

• Divide 360° by the exterior angle

• Multiply the exterior angle by 360°
