What is a concave polygon?

Back

A concave polygon is a polygon that has at least one interior angle greater than 180 degrees, causing it to 'cave in'.

Front

What is a convex polygon?

Back

A convex polygon is a polygon where all interior angles are less than 180 degrees, and no vertices point inward.

Front

How do you calculate 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 sum of the interior angles of a nonagon?

Back

The sum of the interior angles of a nonagon (9 sides) is (9-2) * 180 = 1260 degrees.

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

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.

Front

How many sides does a pentagon have?

Back

A pentagon has 5 sides.

Front

How many sides does a hexagon have?

Back

A hexagon has 6 sides.

Front

What is the value of v in a triangle with angles 60, 67, and v degrees?

Back

The value of v is 53 degrees, since the sum of angles in a triangle is 180 degrees.

Front

What is the exterior angle of a polygon?

Back

An exterior angle of a polygon is formed by one side of the polygon and the extension of an adjacent side.
