So the correct answer is Option A. Chief among these are working with symmetry in sketches. Help them gain a better comprehension in identifying, drawing and labeling points, lines, rays, and line segments. So we know that only the straight line which passes through the centre of the line segment at right angle divides the line segment in the two similar or identical halves, which means that the line of symmetry of a line segment is the perpendicular bisector of the line segment. Geometry 6. It is the same as basic symmetry which tells us that if the dotted line divides the image into two equal halves then it is the reflective symmetry of the figure. N/A. Only convex polygons can be regular. This is important because when we partition (or divide up) the Line Symmetry A figure in the plane has (or reflection symmetry) if the figure can be mapped onto itself by a reflection in a line, They also draw each item.
