[b]Directions:[/b][br][br]When 2 lines intersect, 4 angles form. Determine if when two line intersect, will it [b]always, sometimes or never[/b] create two pairs of equal angles.[br][br]Interact with the following applet for a few minutes, then answer the questions that follow.
Complete the following statement (based upon your observations). [br] [br] [color=#b20ea8][b]Two intersecting lines will ___________________ create two pairs of equal angles.[/b][/color]
Suppose the pink angle above measures 140 degrees. What would the measure of its pair angle?
What would be the measure of the other 2 (gray) angles if the pink measures 140 degrees?
What do you think we could call these types of angles?
Do the three intersecting lines create pairs of equal angles?
