do the cha cha slide
A triangle is translated (x + 2, y - 10) and then rotated 90 degrees. If the triangle starts at A(-4, -2), B(3,4), C(-5, 6), where does the triangle end it's journey? Structure your answer as A"(x,y), B"(x,y), C"(x,y)
(a)
How do you get from the red triangle to the orange triangle?
reflection over the y-axis and then the x-axis
rotate 270 degrees and reflect over y = 2
reflection over the y-axis and translate up 7
rotate 180 degrees and reflect over y = 2
translate up 7, translate right 6, and then reflect over the x-axis
