Exploring Lines of Symmetry in Shapes

What is a line of symmetry?

• A line that cuts through the shape's center

• A line where shapes on either side are mirror images

• A line dividing a shape into unequal parts

• A line that connects opposite corners of a shape

What is the significance of symmetry in nature and mathematics?

• It represents balance and harmony

• It indicates chaos

• It is purely aesthetic

• It has no real significance

Why is a certain line not considered a line of symmetry in a rectangle?

• Because it only touches one corner of the rectangle

• Because it is diagonal

• Because the shapes on either side are not mirror images

• Because it divides the rectangle into two unequal parts

Why does a parallelogram have no lines of symmetry?

• Because it has unequal sides

• Because the opposite sides are not parallel
