Question

1. how many lines of symmetry does the following figure have? 3 1 4 5

Explanation:

Step1: Recall the definition of line of symmetry

A line of symmetry is a line that divides a figure into two congruent (identical) parts.

Step2: Analyze the given equilateral - triangle

For an equilateral triangle, we can draw a line of symmetry from each vertex to the mid - point of the opposite side.

Since an equilateral triangle has 3 vertices, and for each vertex, there is a unique line of symmetry passing through it and the mid - point of the opposite side.
