What is a convex polygon?

Back

A convex polygon is a polygon where all interior angles are less than 180 degrees, and no line segment between any two points on the boundary ever goes outside the polygon.

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 in a kite, the diagonals bisect each other.

What are the characteristics of a polygon?

Back

1. It is a closed figure. 2. It is two-dimensional or flat. 3. It has straight sides. 4. It has three parts: sides, vertices, and angles.

Front

What is a concave polygon?

Back

A concave polygon is a polygon that has at least one interior angle greater than 180 degrees, causing at least one vertex to point inward.

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

Front

How do you find the missing angle in a trapezoid?

Back

To find the missing angle in a trapezoid, use the property that the sum of the interior angles of any quadrilateral is 360 degrees.

Front

What is the formula for the area of a trapezoid?

Back

The area of a trapezoid is given by the formula: Area = (1/2) × (Base1 + Base2) × Height.

What is the difference between a regular and irregular polygon?

Back

A regular polygon has all sides and angles equal, while an irregular polygon has sides and angles that are not all the same.
