Lets start with the basics...

My Name is Emily Robinson.

I am...

* A once fearful student of math, now trying to master it to help other fearful students feel confident in Mathematics.

* A Student at Mesa Community College, going to transfer to ASU next year.

*An aspiring first, second, or third grade teacher.  (Haven't decided yet!)

*an optimist, and love doing things that make myself and others happy.

* I hope you learn a little something about Geometry from the blog :o)

Just for giggles...

More Blogs to use as a resource and that I enjoyed :)

Finding the sum of the interior angles of a regular n-gon...

(n-2)180 degrees.

So lets apply this! 

Say you have a decagon...




Decagon has 10 sides, so lets plug that into the formula for "n."

(10-2)180 

10-2= 8

180 times 8= 1440.

So to find each interior angle you...

1440/ 10= 144 degrees. 

We can conclude each interior angle is 144 degrees. 

Did you know...

That we can determine if a triangle is possible from having the degree of two different angles? 

Lets try it!

Example:

We have an angle that is 30 degrees, and an angle that is 50 degrees...

50+30= 80 degrees is the sum of those two angles, that is less than 180 so that means it can make another angle to form a triangle. 

Now we have to subtract the sum from 180 degrees to find that third angle! 

READY STEADY GO...

180-80= 100 degrees, so this is the third angle. 

WE HAVE JUST FOUND A TRIANGLE!!
