[chorus]

Triangles, 3 sides, 3 angles.

Triangle is a polygon, triangle is a polygon.

[verse]

An acute triangle has 3 angles

that are less than 90 degrees.

An obtuse triangle has 3 angles

but 1 angle is more than 90 degrees.

A right triangle has 3 angles

but 1 angle equals 90 degrees.

An equilateral triangle has 3 sides,

and all 3 sides are equal.

Isosceles triangle has 3 sides,

but only 2 of those sides are equal.

A scalene triangle has 3 sides.

All 3 sides have different sizes.

Benjamin Franklin

(chorus)

(verse1)

Benjamin Franklin invented bifocals

Bifocals or glasses, if you don’t know

Benjamin wanted to prove that lightning is electricity

So Benjamin conducted a famous kite experiment with a key

Benjamin helped to start America’s first library

He helped to put streetlights and paved roads in Philadelphia, the city

The Declaration of Independence was partly written by Benjamin

Benjamin also signed the United States Constitution

Benjamin Franklin was a scientist and an inventor

Benjamin Franklin was a writer and a leader

Benjamin Franklin’s face is on the hundred bill I spent

What Benjamin Franklin was not? He was not President
