Int 2 Winter Final Review (Pt 2)

Front

What is an exterior angle of a polygon?

Back

An exterior angle is formed by one side of a polygon and the extension of an adjacent side. The sum of the exterior angles of any polygon is always 360°.

Front

How do you find the number of sides of a regular polygon given an exterior angle?

Back

To find the number of sides (n) of a regular polygon, use the formula n = 360° / exterior angle.

Front

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

Back

The sum of the interior angles of a polygon with n sides is given by the formula (n - 2) × 180°.

Front

What shape has 4 sides and two sets of parallel sides?

Back

A rectangle or a square.

Front

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

Is a square a type of rhombus?

Back

True. A square is a special type of rhombus where all angles are right angles.

Front

What is a polygon?

Back

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

Front

What is the difference between a rectangle and a square?

Back

A rectangle has opposite sides equal and all angles are right angles, while a square has all sides equal and all angles are right angles.

Front

How many sides does a polygon have if each exterior angle measures 40°?

Back

9 sides.

Front

What is the measure of each interior angle of a regular polygon with 9 sides?

Back

Each interior angle measures 140°.
