(NEED HELP ASAP)

Triangle PQR was dilated according to the rule DO,2(x,y)(2x,2y) to create similar triangle P'Q'Q.

Which statements are true? Check all that apply.

∠R corresponds to ∠P'QQ'.
∠PQR corresponds to ∠QPQ'.
Segment QQ' is parallel to segment PP'.
Side RQ corresponds to side QQ'.
△PQR ≅ △P'Q'Q

Answer 1

Explanation:

The answer is 1 and 4 are correct.

Answer 2

The correct option is 1 and 4 are correct.

Explanation:

The dilation is the enlargement and comparison of a figure according to the scale factor from the given center of dilation.

The rule DO,2(x,y)(2x,2y) express the dilation with factor 2 and the center of dilation is origin. It shows the enlargement of the triangle. The sides of image is twice of the preimage.

In dilation the corresponding angles remains same and the corresponding sides are equal.

`\angle P=\angle P'`

`\angle PQR=\angle Q'`

`\angle R=\angle P'QQ'`

`PR=P'Q`

`PQ=P'Q'`

`RQ=QQ'`

Therefore option 1 and 4 are correct.
