Similarity & Dilations Practice

Based on the given notes, find the coordinates of A' if a figure

centered at (0,0) has a scale factor (k) of 1/2 and a point at A(6, -4).

**Please type your answer with parentheses and no spaces

Please type the scale factor as a fraction in simplest form.

Determine whether the dilation from triangle ADC to triangle PQR

is an enlargement or reduction and then find the scale factor.

*Type your answer as a fraction in simplest form

Type the coordinates of each image point

in the order of T', R', and S'

*Please use parentheses separated by a comma

for each answer with NO SPACES

Type the coordinates of each image point in the order

of A', B', and C' with parentheses and separated

by commas (no spaces)

Type the coordinates of each image point in the order

of X', Y', and Z' with parentheses and separated

by commas (no spaces)

△A′B′C′ is the image of △ABC after a dilation. Describe the dilation and provide k.

• reduction; k=1/2

• reduction; k=1/3

• enlargement; k=3

• enlargement; k=2

△L′M′N′ is the image of △LMN after a dilation. Describe the dilation and provide k.

• enlargement; k = 3

• reduction; k = 1/3

• enlargement; k = 2

• reduction; k = 1/2

△D′E′F′ is the image of △DEF after a dilation. Describe the dilation and provide the scale factor.

• reduction; k = 1/3

• enlargement; k = 3

• reduction; k = 1/2

• enlargement; k = 2

Type the coordinates of each image point in the order

of W'', X'', Y'', and Z'' with parentheses and separated

by commas (no spaces)
