Given points a(0,3) b(-1,4) c(2,-1). what is coordinate b’ if the figure is rotated counter-clockwise 90 degrees? a• (4,-1) b• (-4,-1) c• (4,1) d• (1,-4)

The answer is (C) (4,1).

Step-by-step explanation:  Given points are A(0,3), B(-1,4) and C(2,-1). Obviously, these points will form a triangle. We need to find the co-ordinates of the point B', which is formed after rotating the figure counter-clockwise 90 degrees.

The point B(-1,4) lies in the second quadrant. After rotating 90 degrees counter-clockwise, the this point will lie in the first quadrant. So, both the x-coordinate and y-coordinate will be positive. Also, the two coordinates will exchange. Please see the attached figure.

Thus, the coordinates of point B' are (4,1).

Hence, (C) is the correct option.

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
