What is symmetry?

• Symmetry is a concept that only applies to art and design, not science.

• Symmetry is a term used only in mathematics and has no real-world applications.

• Symmetry is a chaotic and unbalanced arrangement of parts.

• Symmetry is a balanced and harmonious arrangement of parts on either side of a central line or point.

We can make a symmetrical lines?

• We can make symmetrical lines by drawing mirror images on both sides of the line.

• Symmetrical lines are always straight

• Symmetrical lines can only be created using a ruler

• Symmetrical lines are only possible in 2D space

What is a reflection symmetry?

• reflection symmetry is when a figure can be reflected over a line and still look the same.

• reflection symmetry is when a figure can be rotated over a point and still look the same.

• reflection symmetry is when a figure can be translated and still look the same.

• reflection symmetry is when a figure can be dilated and still look the same.

What is a rotational symmetry?

• A rotational symmetry is when a shape can be flipped upside down and still look the same.

• A rotational symmetry is when a shape can be stretched or compressed and still look the same.

• A rotational symmetry is when a shape can be rotated less than a full circle and still look the same.

• A rotational symmetry is when a shape can be reflected across a line and still look the same.
