Intersecting Lines
Directions:
When 2 lines intersect, 4 angles form. Determine if when two line intersect, will it always, sometimes or never create two pairs of equal angles.
Interact with the following applet for a few minutes, then answer the questions that follow.
Complete the following statement (based upon your observations). Two intersecting lines will ___________________ create two pairs of equal angles.
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?
Interact with the following applet for a few minutes, then answer the questions that follow.
Do the three intersecting lines create pairs of equal angles?
Complete the following statement (based upon your observations). Thress intersecting lines will ___________________ create pairs of equal angles.
