Question

As usual, I don’t understand the following questions: (Remake)

1.How are the coordinates of the

new point found if it is rotated 90° counterclockwise? How many degrees is that equivalent to if the rotation is clockwise?

2.How are the coordinates of the new point found if it is rotated 180° counterclockwise? How many degrees is that equivalent to if the rotation is clockwise?

3.How would you describe what a rotation is.

4.A triangle has coordinates A (1, 5), B (-2, 1) and C (0, -4). What are the new coordinates if the triangle is dilated with a scale factor of 1/5?

5.A line segment has endpoints P (3, 6) and Q (12, 18) and is dilated so that its new endpoints are P’ (2, 4) and Q’ (8, 12). What is the scale factor? If the length of PQ is 15, what is the length of P’Q’?

6.A triangle has coordinates A (1, 5), B (-2, 1) and C (0, -4). What are the new coordinates if the triangle is rotated 90° clockwise around the origin?

7.How are the coordinates of the new point found if it is rotated 270° counterclockwise? How many degrees is that equivalent to if the rotation is clockwise?

8.How are the coordinates of the new point found if it is dilated with a scale factor of 3?

9.How would you describe what exactly a dilation is (geometry)
