How to determine the missing measures of an isosceles 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.

[@zvti]

i learned way more by this guy than by my math teacher bruh

[@smilingflame3152]

same

[@9a2-h3l]

Lol

[@stephenplowden2820]

I’m just understanding this for the first time in 20 years. More videos Teach

[@SICARIO1k]

Stephen Plowden - Are you learning for fun or did you need to know this for a real life situation

[@thefirst3329]

Omg! Can you upload more content like this?

[@brianmclogan]

I have ton of content on this, at the end of the video there is a playlist with more examples

[@thefacelessnoise.666]

To this day no one knows what was wrong with Zack

[@brianmclogan]

haha

[@jiyajoshi110]

who be watching this during Corona Virus outbreak??

[@unknownj424]

Thanks you this is so helpful

[@brianmclogan]

you are very welcome! happy to be able to help

[@thefirst3329]

Were the angle measures that you solved for at the end equal? Is that another feature of an isosceles trapezoid? And are those specific angles are equal for every trapezoid or For this certain example?

[@brianmclogan]

only for an isosceles trapezoid

[@bbbleeee]

i don't got the other number or like the measure and what I got is just one example or one number as a measure and I want to get the other measure if u know what I mean

[@thefirst3329]

Since you used the alternate interior angle method, why didn't you say that 32 degrees was also the amount of degrees for angle X? And why aren't the angles on a straight line supplementary?

[@1490063]

I think because the 32 degree angle is not touching the parallel lines.

[@davidconstantino6857]

Because line segment kn is not parallel to the opposite side

[@klausoldie4197]

With the specified data, no isosceles trapezoid can be constructed. The values for the base sides and the legs do not match the angles.

[@floofytailz]

Is there a way to do this with a normal trapezoid instead of isosceles?

[@imwayne6543]

How about having measurements and no angles; teach how to determine all angles...

[@AlexandrBorschchev]

Trig algebra + calculator. Easy peasy.

[@ramonaalbitar-dw5mo]

do you learn private online lesson

[@maryamhamidaddin1284]

1:05 I thought opposite angles would be angle KNM and angle KLM and not KNM and LMN.

[@ssekiro8944]

Hey pretty

[@papawolf638]

what if you are given an isosceles trapezoid and you have to find the area, but the variables given, in regards to the parallel sides, the longer base and height. No other information regarding other sides, angles, or diagonals are given. How do you find the missing base? or the area?
Once the missing base is found I know the formula for area.
A=(1/2)(b1+b2)(h)

[@Mal_lows]

what about finding the sides

[@susblasian1433]

How come the 2 angles weren’t 32?

[@kathrynebulger]

Are you a math professor?

[@brianmclogan]

high school teacher

[@2mal977]

how is it 114° if the angle is less than 90°

[@brianmclogan]

picture is not drawn to scale

[@mcrazyprod]

This don't work

[@brianmclogan]

what do you mean?

[@KJ-qb3po]

it is wrong.

[@fanaticcookie8585]

That’s wrong

[@franc1159]

No its perfectly correct, i dont see why you'd think that

[@meelislehtla4952]

When to try draw this trapezoid, lengths and angles doesn't match.
