Question

5. The vertices of AABC are A(-5, 4), B(-2, 4), and C(-4, 2). If AABC is reflected across the y-axis, find the coordinates of the vertex C'.​

Answer 1

• C'(4, 2)

Explanation:

The vertex C has coordinates:

• x = - 4, y = 2

If the triangle reflected over the y-axis, the y-coordinates of C and C' will be same but the x-coordinate will change to opposite.

So the vertex C' will have coordinates:

• x = 4, y = 2
