Scale Factor and Dilation Practice

Are these triangles dilation of each other?

• Yes, because the scale factor is 2.

• Yes, because the scale factor is 0.5

• No, because the scale factor are not the same.

• No, because the scale factor is 3.

Triangle DEF is the image of the dilation of Triangle ABC. What is the length of DF (value of x)?

Triangle DEF is the image of the dilation of Triangle ABC. If the measure of Angle A is 77 degrees, what is the measure of Angle D?

Triangle NOP is dilated using Center N to create Triangle N'O'P'. If the measure of Angle N'O'P' is 41 degrees, what is the measure of Angle NOP?

Figure PQRST is the image of the dilation of Figure ABCDE. What is the length of PQ (value of x)?

Are the two quadrilaterals a dilation of each other?

• No, they are not triangles.

• No, the scale factor are not the same.

• Yes, the scale factor is 1/6.
