Question

The vertices of triangle ABC on a coordinate grid are A(2, 2), B(8, 8), and C(2, 8). The vertices of triangle AQR are A(2,2), Q(4,4), and R(2,4).
Which proportion can be used as a step in proving that triangle ABC is similar to triangle AQR?
AC/AR=3/1
AC/AQ=3/1
BC/QR=6/5
BC/RC=3/2

Answer 1

AC/AR

Answer 2

@ls15580 could you explain? :(

Answer 3

Graph them both and you'll see AC and AR are the same side, write down there lengths and simplify
