Define what a polygon is in geometry.

• A polygon can have an infinite number of sides.

• A polygon is a shape with curved sides.

• A polygon is always a regular shape.

• A polygon is a closed figure with straight sides.

What is the formula to calculate the circumference of a circle?

Explain what parallel lines are in geometry.

• Parallel lines are two lines that are always the same distance apart and will never intersect.

• Parallel lines are two lines that intersect at multiple points.

• Parallel lines are two lines that are perpendicular to each other.

• Parallel lines are two lines that are always converging towards each other.

What is the difference between acute, obtuse, and right angles?

• An acute angle is greater than 90 degrees

• A right angle is greater than 180 degrees

• An obtuse angle is less than 90 degrees

• An acute angle is less than 90 degrees, an obtuse angle is greater than 90 degrees but less than 180 degrees, and a right angle is exactly 90 degrees.

Define what a rhombus is in geometry.

• A rhombus has three sides of equal length

• A rhombus has no angles

• A rhombus is a type of circle

• A rhombus is a quadrilateral with all four sides of equal length.

What is the formula to calculate the volume of a cube?

• V = s^2

• V = 4s

• V = s^3

• V = s

Explain what a perpendicular bisector is in geometry.

• A perpendicular bisector is a line that intersects another line segment at a 90-degree angle and divides it into two equal parts.

• A perpendicular bisector is a line that runs parallel to the line segment it intersects.

• A perpendicular bisector is a line that divides a line segment into three unequal parts.

• A perpendicular bisector is a line that intersects another line segment at a 45-degree angle.

What is the Pythagorean theorem and how is it used?

• The Pythagorean theorem is used to calculate the length of one side of a right-angled triangle when the lengths of the other two sides are known.

• The Pythagorean theorem is used to determine the volume of a rectangular prism.

• The Pythagorean theorem is used to find the sum of angles in a triangle.

• The Pythagorean theorem is used to calculate the area of a circle.
