Question

Reflect traingle ABC with A (3,-1) B(1,-5) and C(-2,-2) in the x-axis. What are the coordinates of B?

Answer 1

B'(1,5)

Explanation:

On reflection about the x-axis the transition rule followed is

`0(x,y)\rightarrow O'(x,-y)`

Given:

`\triangle ABC` is reflected on
`x`-axis.

Points:

`A(3,-1) ,\  B(1,-5)\ and\ C(-2,-2)`

New point
`B'` can be given as:

`B(1,-5)\rightarrow B'(1,-(-5)) =B'(1,5)`
