ΔABC is translated 2 units down and 1 unit left. Then it is rotated 90° clockwise about the origin to create ΔA′B′C′. What are the coordinates of the vertices of ΔA′B′C′ ?
a) A′(2, 0), B′(1, 1), C′(1, 1)
b) A′(2, 1), B′(5, 0), C′(3, 0)
c) A′(1, 2), B′(2, 3), C′(0, 3)
d) A′(2, 1), B′(1, 0), C′(1, 0)

Best ResponseYou've already chosen the best response.0A(01,02) 01 = 1 0  2 = 2 so when A is translated, its ordered pair becomes (1,2)

Best ResponseYou've already chosen the best response.0now we need to rotate that 90 clockwise the rule for that is (y,x)

Best ResponseYou've already chosen the best response.0so if we put the ordered pair for A into (y,x) we get 2, 1

Best ResponseYou've already chosen the best response.0If you want, we can find the ordered pairs for B and C but only 1 answer choice has (2,1) for A

Best ResponseYou've already chosen the best response.0no not A look for A'(2,1)

Best ResponseYou've already chosen the best response.0ordered pair (1,3) 2 units down 32 = 1 1 unit to the left 11 = 0 (0,1) rotation 90 clockwise (1,0) so B'(1,0)
