4. BK has endpoints B(1,4) and K (4-3). Rotate BR clockwise 270 degrees about the origin Part A: Write an algebraic description of the transformation of BK. Part b. what are the endpoints of the newline segment

Respuesta :

The algebraic descriotion is;

R (x,y) = R'(y + 0, 0-x)

The new endpoints of the line BK are B'(4,-1) and K' (-3,-4)

Here, we want to rotate the end points of the line segment at an angle of 270 degrees clockwise about the origin

To rotate a certain point at 270 degrees clockwise about the origin, we have;

R (x,y) to R' (y, -x)

The algebraic description is simply;

R (x,y) = R'(y + 0, 0-x)

To get the new endpoints, we simply write the transformation as shown;

(1,4) becomes (4,-1)

(4,-3) becomes (-3,-4)
