A rectangle is transformed according to the rule R0, 90º. The image of the rectangle has vertices located at R'(–4, 4), S'(–4, 1

zalisa [80]

We are said that a rectangle has been transformed into the one indicated in Figure 1 according to this rule:

$R_0, \ 90^{\circ}$

We know that the center of rotation is origin and two rules are applied to rotate a point 90 degrees, namely:

1. Clockwise

In this case, the rule to transform a point is:

$(x,y) \rightarrow (y,-x)$

This rule was already applied to form the image, so all we need to do is to reverse the answer using this formula, therefore:

$For \ Q(-3,4): \\ \\ (y,-x)=(-3,4) \\ \\ \therefore y=-3 \ and \ -x=4 \therefore x=-4 \\ \\ Thus, \ the \ point \ is: \\ \\ \boxed{Q(-4,-3)}$

2. Counterclockwise

Applying the same previous concept but with the new rules for this case:

$(x,y) \rightarrow (-y,x)$

By reversing the answer, we have:

$For \ Q(-3,4): \\ \\ (-y,x)=(-3,4) \\ \\ \therefore -y=-3 \therefore y=3 \ and \ x=4 \\ \\ Thus, \ the \ point \ is: \\ \\ \boxed{Q(4,3)}$
