G.GCO.1 Angle Bisector Definition (I)
From what you've seen, describe what it means for a ray to bisect an angle. In your description, avoid using the words or phrases "middle", "down-the-middle", "half".
Use the Point on Object tool to plot a point F anywhere on the angle bisector. Use the Angle tool to find and display the measure of angle BAF and CAF. How do these results reflect (i.e. illustrate) your response to (1)?
