Description:
  1.  

    Present how if two lines intersect to form adjacent congruent angles, then the lines are perpendicular ()

  2.  

    Present how if two sides of adjacent acute angles are perpendicular, then the angles are complementary.

  3.  

    Provide examples that demonstrate how to use these theorems about perpendicular lines to make logical arguments, as well as solve for unknown variables and angles.

 

This packet should help a learner seeking to understand the theorems about perpendicular lines.
