1.1 radian and degree measure
... The measure of an angle is determined by the amount of rotation from the initial side to the terminal side. One way to measure angles is in radians. To define a radian, you can use a central angle of a circle, one whose vertex is the center of the circle. Arc length = radius when = 1 radian ...

... Proof: We can find a rigid motion taking side AB to sideXY, and point C to a point C’ on opposite side of line XY from point Z, as usual. Now reflecting in line XY sends side XC’ up to a segment making the same angle as side XZ, hence C’ goes to a point C’’ lying on the line through XZ. Similarly se ...
