## Study Notes

### Types of Prisms and Their Characteristics

- A prism has polygonal faces, including triangles, quadrilaterals, pentagons, and more.
- The shape of a prism's cross-section is the same as the shape of its base.
- A prism can have a circular base, but it is not a polygon, so it's not a typical prism.
- The cross-section of a prism is congruent to the base shape, ensuring that all cross-sections parallel to the base are identical.

### Specific Types of Prisms

- A pentagonal prism has two pentagonal bases and 5 rectangular faces.
- The defining characteristic of a prism's shape is that it has two identical faces, joined by a rectangular solid.

### Calculating Surface Area and Volume

- The formula to find the surface area of any kind of prism is: SA = 2B + Ph, where B is the base area, P is the perimeter, and h is the height.
- The volume of a triangular prism depends on the base area, height, and length of the triangular base.

### Classifying Prisms

- In a regular prism, the angle between the base and the lateral faces determines whether it is classified as a right prism (90Â°) or an oblique prism (not 90Â°).
- An irregular prism is differentiated from a regular prism by its non-identical faces and non-rectangular sides.
- An oblique prism is a prism that is not a right prism, meaning the angle between the base and the lateral faces is not 90Â°.
- The height of a square prism can be determined when given its volume and base area, using the formula: V = Bh, where V is the volume, B is the base area, and h is the height.
