Square KLMN with vertices K(0,2), L(1,8), M(7,7), and N(6, 1): 270 counterclockwise about the orgin

Answer 1

Note: Consider we need to find the vertices of the image.

Given:

Square KLMN with vertices K(0,2), L(1,8), M(7,7), and N(6, 1).

It rotates 270 counterclockwise about the origin.

To find:

The vertices of the image after rotation.

Solution:

If a figure rotates 270 counterclockwise about the origin, then the rule of rotation is defined as

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

Using this rule, we get

`K(0,2)\to K'(2,0)`

`L(1,8)\to L'(8,-1)`

`M(7,7)\to M'(7,-7)`

`N(6,1)\to N'(1,-6)`

Therefore, the vertices of the image are K'(2,0), L'(8,-1), M'(7,-7) and N'(1,-6).
