Best answer 2 votes 2 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 13.1k points comment Share ask related question Follow See all 0 reply Please log in or register to add a comment.
