Chapter 7 Review - Polygons

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments that connect to form a closed chain or circuit.

Front

What is the sum of the interior angles of a polygon with n sides?

Back

The sum of the interior angles of a polygon with n sides is (n-2) × 180 degrees.

Front

What is a trapezoid?

Back

A trapezoid is a quadrilateral with at least one pair of parallel sides.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid in which the non-parallel sides are equal in length.

Front

What is a midsegment in a trapezoid?

Back

The midsegment of a trapezoid is a line segment that connects the midpoints of the non-parallel sides and is parallel to the bases.

Front

How do you find the length of the midsegment in a trapezoid?

Back

The length of the midsegment is the average of the lengths of the two bases: (Base1 + Base2) / 2.

Front

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

Back

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

Front

What is a kite in geometry?

Back

A kite is a quadrilateral with two distinct pairs of adjacent sides that are equal in length.

Front

If AC = 44 in kite ABCD, what is EC?

Back

EC = 22, since diagonals of a kite bisect each other.

Front

What is a regular polygon?

Back

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