You could draw a triangle,
any size, any kind

(go ahead, I’ll wait)

Cut it out, and then tear
off the angles

Put the vertices
on the same point

the sides of your angles
touching each other

and your three angles
make a straight line

Your kids probably did this
in math class

The three angles of triangles
will always add up to 180 degrees

A straight line may also be
measured as 180 degrees

That’s why your angles
made a straight line

A straight angle
classic Euclidean geometry

But, did you know
the sum of angles

of hyperbolic triangles
are less than a straight angle?

And did you know
that an ideal hyperbolic triangle

has a measure
of zero degrees?

Somewhat less
than a straight line

Your kids did not
make one of those in math class

To be honest
it doesn’t make sense to me either

This poem was written in response to the prompt to write a straight line poem at Poetic Asides.
