Best answer 12 12 votes A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly. The least number of squares that must be added $ = 6.$ So, the correct answer is $(C).$ Lakshman Bhaiya answered Mar 22, 2021 • edited Apr 9, 2021 by Lakshman Bhaiya Lakshman Bhaiya comment Share Follow 0 reply Please log in or register to add a comment.
