The equation that describes the line of symmetry in the figure given is: y = 0.
What is a Line of Symmetry?
A line of symmetry can be described as an imaginary line that divides a shape or figure into two equal halves, where each is a mirror image of the other.
The triangle given will be divided into two equal halves by a line of symmetry that runs through the horizontal axis (x-axis).
Equation of the horizontal axis is expressed as y = 0.
Therefore, the equation that describes the line of symmetry in the figure given is: y = 0.
