Front

What is the rule for the translation of a point (x, y) 6 units right and 4 units down?

Back

(x + 6, y - 4)

Front

How do you set up a proportion comparing whole lengths to find the measure of x?

Back

Set up the equation as \frac{whole\ length_1}{whole\ length_2} = \frac{part_1}{x}.

Front

What is the value of x when comparing part to part in a proportion?

Back

x = 4.5

Front

What is the scale factor (k) if the lengths of two similar figures are in the ratio 3:4?

Back

k = \frac{3}{4}

Front

What is the algebraic notation for translating a figure 6 units right and 5 units up?

Back

(x, y) --> (x + 6, y + 5)

Front

Define translation in geometry.

Back

Translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What is a proportion in mathematics?

Back

A proportion is an equation that states that two ratios are equal.

Front

How do you find the scale factor between two similar figures?

Back

Divide the length of a side of one figure by the corresponding side of the other figure.

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size.

Front

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

Back

Area = \frac{1}{2} \times base \times height.
