Symmetry and different types of Symmetry!

What is "symmetry" in geometry?- Symmetry is when one shape becomes exactly like another if you flip, slide or turn it.

So what does that mean?!
Basically, and shape or object that is EXACTLY the same if its split in half.

Are there different types of symmetry?- Yes! And in geometry we will specifically talk about 3 of them!

  1. Line symmetry- A figure has line symmetry if a line can separate the figure into two congruent parts.
  2. Rotational symmetry- If you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has rotation symmetry.
  3. Point symmetry- If a figure or graph is rotated about a point by 180° and yet looks identical to its original, that point is called the Point Symmetry.
