Cross-sections

What is a cross-section?

• A cross-section is the shape that is obtained when a solid is cut through a plane.

• A cross-section is a type of geometric figure that represents a two-dimensional shape.

• A cross-section is a method used to measure the volume of a solid object.

• A cross-section is a visual representation of a solid object from a specific angle.

What shape is the cross-section of a square pyramid when cut vertically through the apex?

• A square

• A rectangle

• A triangle

• A circle

What shape is the cross-section of a square pyramid when cut horizontally?

• A triangle

• A rectangle

• A square

• A circle

How do you find the area of a rectangle?

• Area = length + width.

• Area = length * width.

• Area = length / width.

• Area = 2 * (length + width).

What is the net of a polyhedron?

• A net is a two-dimensional representation of a three-dimensional shape, showing all its faces.

• A net is a solid shape that cannot be unfolded.

• A net is a type of polygon used in geometry.

• A net is a three-dimensional representation of a two-dimensional shape.

What is the cross-section of a rectangular prism when cut parallel to the base?

• A circle

• A triangle

• A rectangle

• A square

What is a plane in geometry?

• A flat, two-dimensional surface that extends infinitely in all directions.

• A three-dimensional object with length, width, and height.

• A curved surface that can be bent or shaped.

• A line that connects two points in space.

What is the cross-section of a triangular prism when cut parallel to the base?

• A rectangle

• A circle

• A triangle

• A square

What is the formula to find the area of a triangle?

• Area = base * height

• Area = 1/2 * base * height

• Area = base + height

• Area = base - height

What is the relationship between the height of a pyramid and its base area?

• The volume of a pyramid is directly proportional to the height and base area.

• The volume of a pyramid is V = (1/3) * base area * height.

• The height of a pyramid is equal to its base area.

• The base area of a pyramid determines its height.
