Question

draw all the lines of symmetry for this equilateral triangle.

Explanation:

Step1: Recall the property of an equilateral triangle

An equilateral triangle has three equal sides and three equal angles.

Step2: Determine the lines of symmetry

A line of symmetry divides a figure into two congruent parts. For an equilateral triangle, the lines of symmetry are the lines that pass through a vertex and the mid - point of the opposite side.

Answer:

An equilateral triangle has 3 lines of symmetry. Each line passes through a vertex and the mid - point of the opposite side.
