# Classifying Triangles Song ```Classifying Triangles Song
A triangle has 3 sides
The angles inside add to 180
There are ways to classify
By their sides
And the angles inside
Isosceles
Scalene
Equilateral
Acute
Obtuse
Or Right Triangle
But we won’t know
Until we know just what that means
Are there no equal sides
Or are there 2 or 3
Are the angles greater than or less than 90
Or is there one that measures exactly
We’ll always be triangles
It’s our polygonal family
If we treat sides equally
Equilateral is what we’d be
We could be scalene
And have no equal sides
Or we can have 2
And be an isosceles
Angles are 89 or less
An acute is what it is
If just 1 is all or greater
It’s obtuse
If it’s 90
It’s the right you’ll choose
Isosceles
Scalene
Equilateral
Acute
Obtuse
Or Right Triangle
But we won’t know
Until we know just what that means
Are there no equal sides?
Or are there 2 or 3
Are the angles greater than or less than 90?
Or is there one that measures exactly
We’ll always be triangles
It’s our polygonal family
If we treat sides equally
Equilateral is what we’d be
We could be scalene
And have no equal sides
Or we can have 2
And be an isosceles
We’ll always be triangles
It’s our polygonal family
If we treat sides equally
Equilateral is what we’d be
We could be scalene
And have no equal sides
Or we can have 2
And be an isosceles
