Question

draw all the lines of symmetry for this shape.

Explanation:

A line of symmetry divides a shape into two mirror - image halves. For the given "U" - shaped figure, we can visualize a vertical line passing through the center of the "U". When we fold the shape along this vertical line, the left and right parts of the "U" will overlap exactly.

Answer:

Draw a vertical line passing through the mid - point of the top horizontal part of the "U" - shaped figure. This vertical line is the line of symmetry for the given shape.
