FLASHCARD QUESTION
Front
If a polygon has 10 sides, what is the sum of its interior angles?
Back
The sum of the interior angles of a decagon (10 sides) is (10 - 2) × 180° = 1440°.

FLASHCARD QUESTION
Front
What is the relationship between interior and exterior angles of a polygon?
Back
The interior and exterior angles of a polygon are supplementary, meaning they add up to 180°.

FLASHCARD QUESTION
Front
How many sides does a polygon have if the measure of one exterior angle is 30°?
Back
To find the number of sides, use the formula: n = 360° / exterior angle. For 30°, n = 360° / 30° = 12 sides.
