Study Notes

Geometric shapes are simply shapes without any mathematical attachment to them.
Examples of geometric shapes include circles, triangles, squares, octagons, and even curvy shapes.
Geometric shapes can be found everywhere, including in the shapes of objects, shadows, and more.

A line of symmetry is a line in a shape that splits the shape in half, making each half a mirror image of the other.
The line of symmetry in a circle is the line that cuts the circle in half and goes through the center of the circle.
Geometric shapes can have more than one line of symmetry.
A circle has an infinite number of lines of symmetry because it can be folded in many ways, as long as the fold goes through the center of the circle.

A rectangle has two lines of symmetry, allowing it to be folded in half sideways and either up or down.
The capital letter A has one line of symmetry, allowing it to be folded in half sideways so that the halves match up perfectly.
There are many other shapes that have lines of symmetry, and discovering them can be done by folding and exploring different shapes.
