Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter P of a rectangle is given by the formula P = 2(l + w), where l is the length and w is the width.

Front

What does it mean for two shapes to be similar?

Back

Two shapes are similar if they have the same shape but not necessarily the same size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

If two triangles are similar, how do you find the length of a missing side?

Back

To find the length of a missing side in similar triangles, set up a proportion using the lengths of the corresponding sides.

Front

What is the relationship between the sides of similar rectangles?

Back

The ratios of the lengths of corresponding sides of similar rectangles are equal.

Front

How do you calculate the cost price from the selling price using a markup formula?

Back

If P = c + \frac{1}{3}c, then c = \frac{P}{\frac{4}{3}}.

Front

What is the parent function of absolute value?

Back

The parent function of absolute value is f(x) = |x|.

Front

How does the graph of g(x) = |x - 2| differ from the parent function?

Back

The graph of g(x) = |x - 2| is the graph of the parent function f(x) = |x| shifted 2 units to the right.

Front

What is the formula for finding the area of a rectangle?

Back

The area A of a rectangle is given by the formula A = l * w, where l is the length and w is the width.

Front

What is the significance of the scale factor in similar figures?

Back

The scale factor is the ratio of the lengths of corresponding sides of similar figures, which helps in determining the size relationship between the figures.

Front

How do you determine the missing side of a right triangle using the Pythagorean theorem?

Back

In a right triangle, if a and b are the lengths of the legs and c is the length of the hypotenuse, then a^2 + b^2 = c^2.
