Answer 1

We have six points that fall in a figure

The original coordinates of this points are:

A: ( -3, 2)

B: ( -3, -4)

D: ( 1, 3)

E: (7, 2)

V: ( 4, 8)

R: ( 3, -2)

To find the new coordinates we must bear in mind that the points must be rotated 90° clockwise.

So, we need to use the next formula to find the new points:

$P(x,y)\to-90^{\circ}\to P^{\prime}(y,-x)$

Finally,

The new coordinates of the points are:

A': ( 2, 3)

B': ( -4, 3)

D': ( 3, -1)

E': ( 2, -7)

V': ( 8, -4)

R': ( -2, -3)
