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

Ha! What a teacher-y take on the straight line prompt. Well done! 🙂

Paula, thank you. I sometimes wear my influences on my sleeve.
