What are Complementary and Supplementary Angles in Geometry? - [5]

In this lesson, we will begin the discussion of geometry by learning how two angles can be complementary to each other or supplementary to each other. Two angles are complementary if they add to 90 degrees. Two angles are supplementary if they add to 180 degrees. Here we will solve several problems that involve diagrams that have either a complementary pair or supplementary pair of angles. We will have to solve for the unknown angle by using these facts. We will also explore the related ideas of vertical angles and adjacent angles.

You are the best mathematic teacher I've ever seen without doubt u are the best👍👍

[dalitson]

You are the best maths teacher, I wish I had teacher like you in Malawi

[elnazfaizi]

watching these videos are better than going to math class cause you can get everything in a short and specific video

[rnnumi]

Watch you every morning before I got to bed. Gives me something to think about. Just wanted to say thank you.

[elccan]

Thank you for the lecture today teacher 😃

[marshel]

U r the best of the best role model of any teacher out there.

[MID]

I'm a Korean and your explanation is perfect to international so Thank you!!

[eccentricorgan]

Learn something new everyday, thanks for sharing this!

[rajakumarchoudhary]

Wow you are the best world teacher in the world

[ali]

You are the best! Thanks for sharing your skill and knowledge for free with us on YT!

[uriahwingfield]

Your videos helped me with my math homework during quarantine I got a B+ in that class thank you.

[rajakumarchoudhary]

I understand all think thank you so much 😚😚😀😀😀

[LQVEGA]

Nice it's easy to understand by an elementary student..Thanks sir..God bless

[memorizer]

Out of curiosity, are you a school teacher? Also, fantastic video! You are a wonderful teacher!!!

A line drawn perpendicular to the straight horizontal line both side we will get 2 right angles
Means 180 degree
It is known as straight angle 👍

[oamesbiblicalscripturesint]

The best teacher I ever hade I thank you.

[sea]

The way you teach makes me miss school.

[ephraimshibru]

God bless you, but i can not learn step by step all of your education but i like, what shall i do to learn?pelase!

[dido]

I enjoy watching your show and always learning from you. I would like to know if there is a symbol to indicate an angle is straight angle. It would be difficult to know if I'm looking at a draft if an angle that is off by 1 or 2 degrees.

If two angles are equivalent and supplementary.find the angles measure.
X+X=180°
2X=180°
X=90°.
One aspect of our study is practicality. It doesn't necessarily mean justifying the facts, verifying the truths and proving theorems. It is about how we apply our knowledge to solve the real life problems (specific) and come easier with it.
