Front

What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

What is the formula to find the interior angle of a regular polygon?

Back

The formula is (n-2) * 180° / n, where n is the number of sides.

Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180°.

Front

What are the interior angles of a triangle?

Back

The interior angles of a triangle are the angles formed inside the triangle by its sides.

Front

How do you find the measure of one interior angle of a regular heptagon?

Back

Use the formula: (7-2) * 180° / 7 = 128.57°.

Front

What is a polygon?

Back

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

Front

What is a regular polygon?

Back

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

Front

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

Back

The sum of the interior angles of a quadrilateral is 360°.

Front

What is the exterior angle theorem?

Back

The exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two opposite interior angles.

Front

What is the relationship between the angles in a triangle?

Back

The angles in a triangle are related such that the sum of the angles is always 180°.
