Question

HELP AM BEING TIMED !!!!

Triangle GFH has vertices G(2, –3), F(4, –1), and H(1, 1). The triangle is rotated 270° clockwise using the origin as the center of rotation. Which graph shows the rotated image? On a coordinate plane, triangle G prime H prime F prime has points (negative 3, negative 2), (1, negative 1), (negative 1, negative 4). On a coordinate plane, triangle G prime H prime F prime has points (3, 2), (negative 1, 1), (1, 4). On a coordinate plane, triangle G prime H prime F prime has points (2, negative 3), (1, 1), (4, negative 1). On a coordinate plane, triangle G prime H prime F prime has points (2, 3), (4, 1), (1, negative 1).

Answer 1

option B

Explanation:

I just the test and got it right.

Answer 2

Option B.

Explanation:

It is given that triangle GFH has vertices G(2, –3), F(4, –1), and H(1, 1).

The triangle is rotated 270° clockwise using the origin as the center of rotation. So, rule of rotation is defined as

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

Now,

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

`F(4,-1)\to F'(1,4)`

`H(1,1)\to H'(-1,1)`

So, the vertices of image are G'(3,2), F'(1,4) and H'(-1,1).

Therefore, the correct option is B.
