Determining the missing angle of a trapezoid

👉 Learn how to solve problems with trapezoids. A trapezoid is a four-sided shape (quadrilateral) such that one pair of opposite sides are parallel. Some of the properties of trapezoids are: one pair of opposite sides are parallel, etc. A trapezoid is isosceles is one pair of opposite sides are equal. A trapezoid is a right trapezoid if one of the angles is equal to 90 degrees.

Given expressions representing some of the parts of a parallelogram, we can evaluate the expressions using our knowledge of the properties of a parallelogram.

I wish you were my Geometry teacher! I learned so much from this 4 minute video than in 90 minutes.

Why do YouTube videos always help more then my actual teachers?

[juanj]

thanks they're really kicking it up at my preschool

I love this guy man been watching him since 7th grade

Thanks for this, it's on my upcoming algebra test and I needed to learn this!

[kellyho]

This was so helpful! Thank you so much sir!

I love your content you explain things in a way I can understand. Currently trying to get promoted at work but am having a hard time solving this problem regarding right trapezoids.

I am currently trying to figure out the lengths of a smaller similar right trapezoid preferably with the same angles ;)


A= Bottom 36
B = Long Side 41.375
C = Short side 36.3125
D = Top angled side 36.354

Originally
I was only given three sides and used Pythagorean theorem to find Side D

Now I need to find out all the sides and preferably the angles if the bottom is 35.125 or 7/8 of an inch smaller, Or the ratio is .976 Any help would be greatly appreciated. Been working on this problem for over 2 months now watching all your videos that I think

do you teach private online sessions ?

[johnhouston]

Good video, will never use in real life. Takes me back to my hippy days in high school

[lantana]

Thank you for posting these videos they help me so much.

Thank you so much, this video was was easy to understand!

How to find angles in trapezium if adjacent angles between 2 parallel side is given?

Problem

In your trapezium cdef
If angle CFE and angle DCF is given then how to find angle def and angle edc?

[harrymatabal]

With due respect how can you find the size of an angle which is missing.

If he was only my math teacher, , he so cool

[hannaharun]

Thanks Fourth Grade Advanced Math is HARD!!

[vintriloquism]

I know how to do it, I just don’t know how to look at it, and that’s key.

[rayb]

wow, the 125 angle sure seems bigger than the 140
