Mr. Gainor Angle Sum Lesson

by Booker Gainor

2

  • The angles inside a polygon are

    called interior angles.

  • When the

    sides of a polygon are extended,

    other angles are formed. The angles

    outside the polygon that are

    adjacent to the interior angles

    are called exterior angles.
