### Polygonsby Keelan Boyle

Rectangles can be all sizes!

Right triangle

Isosceles triangle

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

Equilateral triangles

Squares have to have four right angles and their sides are exactly even.

Circles have no angles!

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.

A hexagon is a shape with six sides and six angles!

A pentagon is a Polygon with five sides!

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.

### ANGLES

This is a right angle. They are exactly 90 degrees.

This is an acute angle. An acute angle Is less than 90 degrees.

This is an Obtuse angle. An Obtuse angle is more than 90 degrees and less than 180 degrees.

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

The two marked are vertical angles

This is a reflex angle. A reflex angle is between 180 and 360 degrees

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.
