Question

coordinates of vertices of triangle abc are a(1,2) ,b(2,2) ,c(2,1) enlarge the given figure by scale factor 3 with origin as centre of enlargement.​

Answer 1

Answer:

Step-by-step explanation:

Formula of dilation with center at origin (x, y) ----> (kx, ky)

If k = 3, then

A(1, 2) ----> A'(3, 6)

B(2, 2) ----> B'(6, 6)

C(2, 1) ----> C'(6, 3)

Answer 2

Answer:A=(4, 8), B=(8, 8), C=((8, 4)
