Question

draw all the lines of symmetry for this shape.

Explanation:

Step1: Recall line - symmetry concept

A line of symmetry divides a shape into two congruent parts.

Step2: Analyze the semi - circle

For a semi - circle, there is one line of symmetry. It is the perpendicular bisector of the diameter. This line divides the semi - circle into two mirror - image halves.

Answer:

Draw a line that is the perpendicular bisector of the straight - line segment (diameter) of the semi - circle. This is the only line of symmetry for the semi - circle.
