It is called the HINGE theorem, because...

• the vertex of the angle acts like a hinge to open the triangle.

• it's named after Joseph Hinge, the man who discovered it.

• "hinge" is the Spanish word for angle.

• the triangle makes a hinge shape, like a tent.

Compare measure of angle Y and measure of angle M.

• measure of angle Y = measure of angle M

• measure of angle Y > measure of angle M

• measure of angle Y < measure of angle M

• Not enough information is given.
