Question

1. describe a sequence of transformations that maps ∆ ABC to ∆ A’ B’ C’.

Answer 1

Answer:

See below

Step-by-step explanation:

1. First (x+10,y), -> (x,-y)

You add +10 to the x of each point moving the triangle horizontally and then you reflect it across the x-axys.

2.

a) Original point (5,3) -> (x+5,-y )

(5+5, 3(-1)) = (10, -3)

b) Original point (-2,7) -> (x+5, -y)

(-2+5, 7(-1)) = (3, -7)

3. The rule for counterclockwise rotation 90° is (x,y) -> (-y,x )

P = (1, -1) -> (1, 1)

Q = (3, -2) -> (2, 3)

R = (3, -4) -> (4, 3)
