Question

The vertices of triangle ABC are A (0,5), B (3,5), and C (2, 2). If the triangle is reflected acrossy-axis, then find the coordinates of the triangle ABC.

Answer 1

`\begin{gathered} A^(\prime)(0,5) \\ B^(\prime)(-3,5) \\ C^(\prime)(-2,2) \end{gathered}`

Explanation:

We have the triangle ABC with the following vertices:

`\begin{gathered} A(0,5) \\ B(3,5) \\ C(2,2) \end{gathered}`

The rule of reflection across the y-axis is the following:

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

We apply and we would be:

`\begin{gathered} A(0,5)\rightarrow A^(\prime)(0,5) \\ B(3,5)\rightarrow B^(\prime)(-3,5) \\ C(2,2)\rightarrow C^(\prime)(-2,2) \end{gathered}`
