Geometry Final Exam Review

Front

What is the formula for the area of a sector?

Back

The area of a sector can be calculated using the formula: \( A = \frac{\theta}{360} \times \pi r^2 \), where \( \theta \) is the angle in degrees and \( r \) is the radius.

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 given by the formula: \( (n-2) \times 180 \) degrees.

Front

What is the area of a circle?

Back

The area of a circle is calculated using the formula: \( A = \pi r^2 \), where \( r \) is the radius.

Front

Define alternate interior angles.

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines it intersects. They are equal when the lines are parallel.

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What is the relationship between the diagonals of a rectangle?

Back

The diagonals of a rectangle are congruent, meaning they are of equal length.

Front

What is the area of a triangle?

Back

The area of a triangle can be calculated using the formula: \( A = \frac{1}{2} \times base \times height \).

Front

What is the formula for the circumference of a circle?

Back

The circumference of a circle is calculated using the formula: \( C = 2\pi r \), where \( r \) is the radius.

Front

What is a rhombus?

Back

A rhombus is a type of parallelogram where all four sides are of equal length.

Front

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

Back

The sum of the interior angles of a hexagon is 720 degrees.
