Flashcard 6-1 to 6-3 Polygons and Parallelograms

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments connected end to end.

Front

Define a parallelogram.

Back

A parallelogram is a quadrilateral with opposite sides that are both equal in length and parallel.

Front

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

Front

How do you find the measure of one interior angle of a regular polygon?

Back

Front

What is the relationship between the angles in a parallelogram?

Back

In a parallelogram, opposite angles are equal, and adjacent angles are supplementary (add up to 180°).

Front

If one angle of a parallelogram is 95°, what is the measure of the opposite angle?

Back

The opposite angle is also 95°.

Front

What is the measure of the exterior angle of a polygon?

Back

The measure of an exterior angle of a polygon is equal to 180° minus the measure of the corresponding interior angle.

Front

How do you calculate the sum of the exterior angles of any polygon?

Back

The sum of the exterior angles of any polygon is always 360°.

Front

What is a regular polygon?

Back

A regular polygon is a polygon with all sides and all angles equal.

How many sides does a 22-gon have?

Back

A 22-gon has 22 sides.
