What is true about the rotation of the shaded triangle to the position of the unshaded triangle? Check all that apply.1.The rotation uses the rule (x, y)g(–x, –y).2.The rotation uses the rule (x, y)g(y, –x).3.The rotation is 90° clockwise about the origin.4.The rotation is 180° about the origin.5.The rotation uses the rule (x, y)g(–y, x).6.The rotation is 90° counterclockwise about the origin.
Question
Answer:
the answers are the options1.The rotation uses the rule (x, y)g(–x, –y).
4.The rotation is 180° about the origin.
ooordinates blue triangle
A(1,1) B(1,3) and C(-5,3)
ooordinates red triangle
X(-1,-1) Y(-1,-3) and Z(5,-3)
let's check
coordinates blue triangle
A(1,1) B(1,3) and C(-5,3)
using the the rule ---- > (x, y)----------------- >g(–x, –y).
A(1,1)------------------ > A1(-1,-1)
B(1,3)------------------ > B1(-1,-3)
C(-5,3)------------------ >C1(5,-3)
therefore
∆A1B1C1=∆XYZ ------------------- > is ok
