Question

The vertices of APQR are P(-3, 8) Q(-6,-4), and R(1, 1). If you reflect APQR across the x-axis, what will be the coordinates of the vertices of the image AP'Q'R'?

Answer 1

Answer:(-3,-8),(-6,4),(1,-1)

Explanation:

Given

Vertices of the triangle are

`P(-3,8), Q(-6,-4),R(1,1)`

Coordinates (a,b) when reflected about x-axis is given as (a,-b) i.e. Y coordinate changes its sign

`\therefore P\rightarrow P'(-3,-8)\\\Rightarrow Q\rightarrow Q'(-6,4)\\\Rightarrow R\rightarrow R'(1,-1)`
