Intersecting Points on a Plane

Intersecting Points on a Plane

• You need to know how to find and identify the
  location where two points intersect (meet) on a
  plane.

2
Lets Review.

• - Which axis is x?
• - Which axis is y?

3
Lets Review.

• - Which quadrants are positive?
• - Which quadrants are negative?

4
Lets Review.

• Points on a plane are always read x, y
• Example -3, 3

Its a scavenger hunt!!

• Object
• Find as many different examples of parallel
  angles in the classroom as you can.
• Rules
• - NO RUNNING, PUSHING, HORSEPLAYING
• - Keep your list on a piece of paper NO
  sharing!
• - No moving chairs, desks.
• - This must be done QUIETLY!
• The student with the longest list will receive a
  prize tomorrow!
