Question

Which shows the image of quadrilateral ABCD after the transformation R0, 90°?

On a coordinate plane, a rectangle has points A (negative 1, 0), B (0, negative 1), C (negative 2, negative 3), D (negative 3, negative 2).

On a coordinate plane, a rectangle has points A prime (0, negative 1), B prime (1, 0), C prime (3, negative 2), D prime (2, negative 3).

Answer 2

A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)

Explanation:

The coordinates of rectangle ABCD are A(-1,0), B(0,-1), C(-2,-3), (-3,-2).

The mapping for a rotation through 90° clockwise about the origin is

`(x,y)\to ( - y,x)`

Therefore:

`A(-1,0)\to A'(0,-1)`

`B(0,-1)\to B'(1,0)`

`C(-2,-3)\to C'(3,-2)`

`D(-3,-2)\to D'(2,-3)`

Therefore the image rectangle has coordinates:

A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)

The first choice is correct.
