Question

how many lines of symmetry does this shape have?

Explanation:

Step1: Define line of symmetry

A line of symmetry is a line that divides a shape into two mirror-image halves that match exactly when folded along the line.

Step2: Analyze the given shape

The shape is a right-angled (L-shaped) figure with two arms of equal length. There is exactly 1 line that can split this shape into two congruent mirror-image parts: a line that bisects the right angle and runs through the midpoint of the "corner" and the midpoint of the imaginary line connecting the ends of the two arms.
