Calculate this reflection of the triangle:

What are the coordinates of the reflected rectangle? ✔ (0,0), (3,0), (0, –2)(0, 0), (0, 3), (–2, 0)(0, 0), (–3, 0), (–2, 0)X (0, 0), (0, –3), (0, –2)

b =

c =

d =

The transformation was a reflection about the ✔ x-axisy-axisline y = xline y = –x.

What are the values for matrix A?:

c11 = c12 = −2

c21 = 5 c22 =

d11 = d12 = 1

d21 = d22 = 1

Are the products equal? Does AB = BA?

a1 = a2 = 58.5

a3 =

c11 = c12 = c13 =

c11 = c12 = c13 =

d11 =

d12 =
