Complementary and Supplementary Angles

Designed by math instructional specialist Emily Kern, this video on Complementary and Supplementary angles presents middle school level concepts in real world terms - ending with three successful techniques for remembering the angles and their properties on big tests.

This is the BEST video for teaching students how to remember these angles! THANK you!

[rjacklin]

Thanks for shooting this video in the "real world." It's helpful for students to see it practically laid out for them.

Your video is really good you are way better than my math teacher.And don't listen to what people say about your video it is really good

[emmicristo]

my teacher made me watch this for hw to complete a worksheet so thanks

[ij]

out of all the videos on youtube yours made the most sense

[markchristian]

Great real world math video. Did you create it? If so, do you have any others? If not, do you know where I can find more math videos like this?

*video made in 2009*





*my teacher in 2020*" leme give this to my students"

There is another way to remember this. C can be changed to a 9 and then the O turn to 0 = CO= 90
S can be changed to 8 L take out the bottom line to become a one 1 and U add a line to make 0=LSU=180

[TheDouceHouse]

Draw a line down the openning of the C and get a 9 in the word Complementary. Not the 9 I just typed, but a 9 with a straight line, not a curved line.

Draw a line connecting both ends of the S and you get an 8 for 180 in Supplementary.

Amazing Video Understand well!
Especially On those 3 Ways to remember angles! Ingenius!
How do you come up with these things?
Thankyou!

[MooMooMath]

Loved the video. Very clear and creative explanation of angles.
I linked your video in my video description.

So nobody gonna talk about how this is from 2009, that house is proud already in 5th grade.

Miss Kern... thank you so much for sharing your knowledge on this subject matter.... From Shreveport, La.... we thank

[timosborn]

In my head it sound like you have to combine rocket science and trigonometry to remember which is complementary and supplementary

[the_ehman]

im in fourth grade and it is a remote learning day and i have to listen to this ughhhh

[NotesBotes]

anyone had to watch this in 2021 bc they teacher

[rosie]
