Question

How do you name the line of symmetry

Answer 1

There is no other name for the line of symmetry, but you might mean something else
Find the line of symmetry by finding the exact point in the middle of the figure
For example, if you folded this figure in half it would be another perfect shape

Answer 2

“To find the line of symmetry graphically, find the vertex, or the farthest point where two lines connect, and write either x = or y = and then insert the x- or y-coordinate. To find the line of symmetry algebraically, you need to identify if the equation is written in standard form or vertex form.”
