Proof: Diagonals of a parallelogram bisect each other | Quadrilaterals | Geometry | Khan Academy

Proving that a quadrilateral is a parallelogram if and only if its diagonals bisect each other

Missed the previous lesson?

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For anyone confused, at 1:20 he meant <DCE not <DEC

[farisnimri]

You taught me what my teacher tried teaching me over the course of a week in 3 mins good looks bro 😎😎😎

[ofir]

At 1:22, does the expression "∠DEC ≅ ∠BAE" wrong? Did he mean "∠DCE ≅ ∠BAE"?

[zainomarks]

9 years later and still my go to guy.Well done champs.

[pizzaz]

I look at my face in ipad rather than studying while wathing this video cause the background is black and i cann see my face cleraly 😂

[harshitpatel]

Corresponding part of congruent triangle ....we use if as

[aimalkhanmusakhel]

Wow ! Khan
Khan's are growing !

[cassiopeia]

i think you meant <DCE instead of <DEC

[rhoadess]

@Nekit1234007 In the video, we can see he meant ∠DCE ≅ ∠BAE, but it's good to point out the error.

[bbbfizzy]

hey isn't it DEC and BAE not DCE and BAE

[sarahnacional]

hmmm triangle should have 3 vertex 2:32 that's vertical angle

[dhruvsinghmalik]

it is angle DCE congruent to angle BAE

[nikjohn]

hey man ur awesome but i cant find perimeter and area of pane figures can u plz send me da video link plzzz

[imrankhan-fqeh]

It would help my daughter 8n her exams

[dinossaurisfinethankyou]

Finally, theres a Diagonal of a parallelogram bisect each other that finding Angles not Linears...

[declan]

Thank you, my teacher can't teach. ;-;

[sanjuverma]

Do the diagonals of parallelogram bisect each angle at vertex?? Please somene clear this ....🙏🙏🙏please yaaron .... Kardo madad

[catnamekabang]

I'm here because of my modules thx for your help

[michaelcabral]

stop being so imature. It's an educational video

[Megaheropap]

They bisect each other but aren’t angle bisector right?
