Right triangle

Isosceles triangle

There are 3 types of triangles: the right, isosceles, and equilateral triangles.

Equilateral triangles

rhombus

A square is a rhombus but a rhombus is not always a square. A rhombus has 4 lines of symmetry and 2 sets of parallel lines.

trapezoid

A Trapezoid has 1 line of symmetry, 2 parallel lines, and 2 intersecting lines.

Octagon

An Octagon is a eight-sided and eight-angled polygon.

The two angles marked are adjacent angles. An adjacent angle is when 2 angles share the same vertex and one side.

Hello, my name is Square. All my four sides are equal and my angles are all right angles. As you can tell I am square as can be. I am getting up because my Momma square is so angled with me. And I have to jump down to get up. I am going down to breakfast. I think I am going to be eating square flakes. They have four lines of symmetry and they are perfectly square like me. I am going to school on the rectangle bus, that oddly enough is a rectangle, which is longer on the top and the bottom than on the front and the back, or visa versa. At school my friend Pentagon, and my friend Triangle, we just call him Tri for short, were at the recess yard with our musical instruments, which are dodecagons, and we went to the auditorium to drop them off. There I noticed there were a bunch of squares binded together with metal rectangles. These are called chairs. Then we went back to the recess yard, which I noticed was a rectangle. Then the bell rang and we lined up to go into school. The end.
