Front

What is the formula for the volume of a rectangular prism?

Back

Volume = length × width × height.

Front

Define surface area in the context of three-dimensional shapes.

Back

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

Front

What is the formula for the surface area of a square pyramid?

Back

Surface Area (S) = base area + 1/2 × perimeter of base × slant height.

Front

What is the relationship between the sides of a right triangle?

Back

In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides (Pythagorean theorem).

Front

What is the formula for the surface area of a cone?

Back

Surface Area (S) = πr² + πrl, where r is the radius and l is the slant height.

Front

How do you find the slant height of a pyramid?

Back

The slant height can be found using the Pythagorean theorem, relating the height, half the base length, and the slant height.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the sine of an angle in a right triangle?

Back

Sine of an angle = opposite side / hypotenuse.

Front

What is the cosine of an angle in a right triangle?

Back

Cosine of an angle = adjacent side / hypotenuse.

Front

What is the tangent of an angle in a right triangle?

Back

Tangent of an angle = opposite side / adjacent side.
