Complementary and Supplementary Angles - Lesson 2

Dear Girls and Boys,

Last lesson was on classifying angles as in Vertical Angles (angles across from each other with intersecting lines) 

Adjacent Angles ( angles next to each other), 

Acute Angles ( angles smaller than 90* ), 

Obtuse Angles ( angles between 90* and 180*), 

Straight Angles ( lines - 180*) and 

the most important of all the Right Angle( angle that measures exactly 90*-sometimes called 90* angle or the corner angle).

  This lesson is on classifying angle pairs - 

COMPLEMENTARY and SUPPLEMENTARY Angles.  Remember when we learned that the 90* angle and the 180* angle were 2 of the most important angles ( most everything is based off of these angles), complementary and supplementary angles are based on these.  Complementary angles are a pair of angles that add up to 90* and Supplementary angles are a pair of angles that add up to 180*.  So be on the lookout for the right angle and the straight angle.

Now this is a proud kid with all the "PODS" he constructed! Now onto the second step to cover the PODS.  The final step in Constructing the Kite is coming up soon.  BUT the fun part is FLYING the KITE!  

Homework: Read the blog, watch the videos and take notes in your graphic organizers and complete the vocabulary on Complementary and Supplementary Angles.
