Question

help plewase cause i dont understandOn a coordinate plane, 2 triangles are shown. The first triangle has points S (3, 5), R (5, 0), and Q (1, 0). The second triangle has points S prime (negative 3, 0), R prime (negative 5, 0), and Q prime (negative 1, 0).Which rule represents R0, 180?(x, y) → (–y, x)(x, y) → (–x, –y)(x, y) → (y, –x)(x, y) → (y, x)

Answer 1

Given that the first triangle has points

`\begin{gathered} S(3,\text{ 5\rparen} \\ R(5,\text{ 0\rparen} \\ Q(1,\text{ 0\rparen} \end{gathered}`

The triangle is as shown below:

The second triangle has points

`\begin{gathered} S^(\prime)(-3,0) \\ R^(\prime)(-5,\text{ 0\rparen} \\ Q^(\prime)(-1,\text{ 0\rparen} \end{gathered}`

Thus, the rule that has RO, 180° is

`(x,y)\to(-x,-y)`
