You could draw four different triangles in a 4-sided polygon, but two are enough to define the polygon.

A ten-sided polygon is called a decagon.
To calculate this, you must find out how many triangles you can draw into the shape. Do this by taking the total number of sides (s) and taking away 2. This leaves you with how many triangles you can draw in the shape (t) from one vertex to another. (Not including outside lines!). Then, multiply the number of triangles in the shape by 180. This leaves you with how many degrees are inside that shape. (a)t = s-2a = t X 180This means there are 1800 degrees in a 12 sided polygon.
A 5-sided polygon is called a pentagon. You can draw up to 5 diagonals in a pentagon.

Draw a nine sided polygon.
A person can draw a five-sided polygon by drawing a pentagon. This is the figure that looks like a house.
To calculate this, you must find out how many triangles you can draw into the shape. Do this by taking the total number of sides (s) and taking away 2. This leaves you with how many triangles you can draw in the shape (t) from one vertex to another. (Not including outside lines!). Then, multiply the number of triangles in the shape by 180.

A 5-sided polygon is called a pentagon. You can draw up to 5 diagonals in a pentagon.
to calculate this, you must find out how many triangles you can draw in to the shape. do this by picking an angle. draw a line to all of the other angles. (for a 12 sided, there would be 9, subtract 3 from any shape to see.) mutiply the number of triangles by 180 degrees. this should be the degrees of the shape. for a 12 sider, the answer would be 1620 degrees.
it's 3 triangles
