What is a prism in geometry?
Click to flip
A prism is a three-dimensional shape with two parallel, congruent bases connected by rectangular or parallelogram-shaped faces.
Click to flip
What are the faces of a prism called?
Click to flip
The faces that connect the two bases are called lateral faces.
Click to flip
How is the surface area of a prism calculated?
Click to flip
The surface area of a prism is the sum of the areas of all its faces, including the bases and lateral faces.
Click to flip
What is the difference between a right prism and an oblique prism?
Click to flip
A right prism has lateral faces that are perpendicular to its bases, while an oblique prism has lateral faces that are not perpendicular.
Click to flip
How do you describe a rectangular prism?
Click to flip
A rectangular prism has bases that are rectangles, and its lateral faces are also rectangles.
Click to flip
What is the formula used to find the volume of a prism?
Click to flip
Volume = Area of Base × Height.
Click to flip
What is the defining feature of a regular prism?
Click to flip
In a regular prism, the bases are regular polygons.
Click to flip
Is a cylinder considered a prism? Why or why not?
Click to flip
Yes, a cylinder is considered a type of prism with circular bases.
Click to flip
What distinguishes a triangular prism from other prisms?
Click to flip
A triangular prism has triangular bases, making its total number of faces 5.
Click to flip
How many edges does a pentagonal prism have?
Click to flip
A pentagonal prism has 15 edges.
Click to flip
Identify the bases of a cube considered as a prism.
Click to flip
In a cube, any pair of opposite faces can be considered as bases because all faces are congruent squares.
Click to flip
What type of prism results when the base is a hexagon?
Click to flip
The prism is called a hexagonal prism.
Click to flip
Describe the cross-section of a prism parallel to its base.
Click to flip
The cross-section is congruent to the base of the prism.
Click to flip
Explain the role of diagonals in understanding prism structure.
Click to flip
Diagonals connect non-adjacent vertices on the same or different faces, helping to understand symmetry and properties of the prism.
Click to flip
How can you differentiate between a prism and a pyramid?
Click to flip
A prism has two parallel, congruent bases, while a pyramid has only one base with all faces converging at a single apex.
