Front

What is a polygon?

Back

A polygon is a closed figure made up of straight line segments. It is two-dimensional and has three main parts: sides, vertices, and angles.

Front

What is a characteristic of a polygon?

Back

A polygon cannot have curved sides.

Front

What is a convex polygon?

Back

A convex polygon is a polygon where all interior angles are less than 180 degrees, and no sides are curved.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid with one pair of parallel sides and the non-parallel sides are of equal length.

Front

How do you find the measure of an angle in an isosceles trapezoid?

Back

In an isosceles trapezoid, the angles adjacent to each base are congruent.

Front

What defines a kite in geometry?

Back

A kite is a quadrilateral with two pairs of consecutive congruent sides.

Front

What is the sum of the interior angles of a polygon?

Back

The sum of the interior angles of a polygon can be calculated using the formula (n-2) × 180°, where n is the number of sides.

Front

What is the difference between a regular and irregular polygon?

Back

A regular polygon has all sides and angles equal, while an irregular polygon does not.

Front

What is a quadrilateral?

Back

A quadrilateral is a polygon with four sides, four vertices, and four angles.

Front

What are the properties of a rectangle?

Back

A rectangle is a quadrilateral with opposite sides equal and all angles equal to 90 degrees.
