Front

What is a net in geometry?

Back

A net is a two-dimensional pattern that can be folded to form a three-dimensional figure.

Front

What three-dimensional figure is formed by a net that consists of 6 square faces?

Back

Cube.

Front

How do you calculate the surface area of a rectangular prism?

Back

Surface area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

What is the formula for the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height.

Front

If the radius of a cylinder is 2 inches and the height is 6 inches, what is the volume?

Back

Volume = π(2)²(6) = 24π ≈ 75.36 cubic inches.

Front

What is the relationship between angles in parallel lines cut by a transversal?

Back

Corresponding angles are equal, alternate interior angles are equal, and consecutive interior angles are supplementary.

Front

If m∠1 = 30°, what is m∠3 if they are corresponding angles?

Back

m∠3 = 30°.

Front

What is surface area?

Back

Surface area is the total area of the surface of a three-dimensional object.

Front

How do you find the surface area of a cylinder?

Back

Surface area = 2πr(h + r), where r is the radius and h is the height.

Front

What is a triangular prism?

Back

A three-dimensional figure with two triangular bases and three rectangular faces.
