The right angle

Hypotenuse

All three of my sides are the same

You'll get the "sine" when you find me over the hypotenuse.

measure me is square units for I cover all

" a cute" angle

Ratio of opposite to adjacent

Two of my sides are more equal than the other

After spending time in the sun, the man had his opposite as well as adjacent sides browned.

My message is clear-bisect my base and multiply by my height

"Oh, probably between 90 and 180..."

Reciprocal of sin

As a triangle, I'm only allowed to have 1 of these

Use me to solve if given only 3 sides

If it's area your "needen" and my angle is right, multiply hypotenuse by the sine to get...

Pi

The "crazy" Greek dude often referred to when solving right triangle problems

The side opposite me is 1/2 the hypotenuse

I consist of 3 ratios, use any two, to solve a triangle when a side or angle is due.

(a squared + c squared - b squared) divided by ( 2 a c)

measured anti-clockwise

I always equal 1

My neighbor and I are the same size. However, our neighbor across the street is twice our size.

If given two sides and an angle to boot, this describes a situation where the number of triangles is in dispute.

If a < 90 and h < a < b, how many triangles would you expect to see?
