Triangle Trouble

Everyone knows Triangle's a bully,
Beats down the sweet squares completely and fully...
Pains the poor polygons, until they say please...
Laughs at them loudly, a 3-sided tease...
Why's he so mean?
This is my theory,
He wants a new side,
And that makes him weary...
Most poly's possess more than 3 sides,
Triangle's left out, Not 'one of the guys,'
He'd like to obtain side number 4,
But as he found out it's hard to get more!
4 sides!

Octagons 8!

Pentagons 5!

He feels so 3rd rate!

He's insecure,
It's always a bug,
triangle wakes up,
And acts like a thug!
But maybe one day,
That 3-sided shape,
Will accept what he is,
And feel really great!

Math Challenges
A triangle is a polygon with 3 sides. How many complete triangles can you make if you had 28 sides?
The 3 angles of EVERY triangle add up to 180 degrees. If a triangle has angles of 35 and 65 degrees, what is the third angle measure?
