Topic 17 Test Review - Polygons and Special Quadrilaterals

What is the sum of the exterior angles of a 20-gon?

Mathematical Equivalence

ON

Determine the measure of x in the regular polygon shown.

This problem is a little harder than you might think at first.

• 108°

• 72°

• 36°

• 90°

Answer explanation

You have to deal with the fact that it's not just one angle.

Find the number of sides of the n-gon if the sum of the measures of the interior angles is 3420.

• 19

• 21

• 17

• 9

• The correct answer is not listed

Answer explanation

I would take 3420/180 (that's how many triangles I have) Add 2 to that to determine the number of sides.
