Question

Reflection across the x or y axis quick check
Triangle ABC is reflected across the x axis if the coordinates of the original shape are A(-4,-1)B (-5,-2) C (-10,-1)what are the coordinates of A,BAndC

Answer 1

When a point is reflected across the x-axis, the x-coordinate remains the same, while the y-coordinate changes sign.

For triangle ABC with the given coordinates:

- A(-4, -1) becomes A'(-4, 1)
- B(-5, -2) becomes B'(-5, 2)
- C(-10, -1) becomes C'(-10, 1)

So, the coordinates after reflection across the x-axis are:
- A'(-4, 1)
- B'(-5, 2)
- C'(-10, 1)
