Question

key vocabulary a figure has in the y -axis or some other vertical line if each half of the figure on either side of the line matches the other side exactly. line symmetry in the y -axis line symmetry in a vertical line other than the y -axis axis of symmetry is x = 0 axis of symmetry is x = 2

Explanation:

The term for a figure having each half on either side of a vertical line (including the y - axis) match exactly is line symmetry. The axis of symmetry for a parabola symmetric about the y - axis is \(x = 0\), and for the second parabola shown, the axis of symmetry is \(x=2\) as indicated by the vertical dashed line.

Answer:

line symmetry
