INSTRUCTIONS

• After you read the page telling you about the
  topic, click the arrow button( ) this will
  take you through some practice problems.

  back to the problem so you can try it again.
• If at any time you wish to return to this screen,
  click on the information button ( ) and
  it will bring you straight here.

Vertical Angles

• Vertical angles are angles that are located
  opposite each other on an intersecting line.
• Vertical angles are also always equal to one
  another.

In this figure, angles BEC and AED are vertical
angles.

Linear Pairs

• A linear pair of angles is formed when two lines
  intersect. Two angles are said to be linear if
  they are adjacent angles formed by two
  intersecting lines. The measure of a straight
  angle is 180 degrees, so a linear pair of angles
  must add up to 180 degrees.

These are examples of a linear pairsnotice that
when you add the angles up together they equal
180.

Resources

• The information featured in this presentation was
  obtained through my personal knowledge (My
  know-how on this subject I am accrediting to
  Mrs. Gatlin and maybe Ill get extra points!) and
  also from various web sites which I found through
  google.com.
• I made all the examples myselfwho knew I was a
  closet computer nerd?
• Hope you enjoyed it!!
