Quadrilaterals L- 4 | Mid Point Theorem & Converse | Proof | Class 9 | Arsh Ma’am | BYJU'S

[@BYJUSClass910]

Hello kids! Check your understanding of the Quadrilaterals chapter by answering these 5 quick questions in the form: forms.gle/wgNDbNijsWhEoAfQA

[@Dhinchak_venu]

13:33 If one pair of opposite sides are equal then it is known as Trapezium 14:35

[@Ishaanagastya]

baka! if the opposite sides are equal then how is it a trapezium, by the statement given by mam it is proved that it is a parallelogram or rectangle or square etc.. visualize to understand. BAKA!😅😂

[@astha--]

Marvelous explanation mam😄 🔴 HOMEWORK- IF PQ=7CM, CP=CQ=3.5cm( SINCE, C IS MIDPOINT) SIMILARLY, PB=BR=4.5cm AND, QA=AR=4cm BY THEOREM: IF MIDPOINTS OF THREE SIDES OF TRIANGLE ARE JOINED FOUR SMALLER TRIANGLES ARE CONGRUENT, IN TRIANGLE ABC, AB=CP=3.5cm BC=QA=4cm CA=BR=4.5cm PERIMETER OF TRIANGLE= SUM OF ALL SIDES... HENCE, PERIMETER OF TRIANGLE ABC= 4+4.5+3.5=12cm(answer)

->Home Work Question "The perimeter of the Triangle ABC is 12 cm, due to Mid-Point Theorum" -> This Class Actually made MPT Very Easy and helped me a lot

[@suganyav9219]

Hw Given : triangle pqr C is the midpoint of pq B is the midpoint of pr A is the midpoint of qr Pq=7cm Qr=8cm Pr=9cm To prove :perimeter of triangle abc Proof Cb=1/2qr(by midpoint theorem) Cb=1/2*8=4cm Ca =1/2pr Ca=1/2*9=4.5cm Ba=1/2pq Ba=1/2*7=3.5cm Perimeter of triangle abc 4+3.5+4.5=12 cm

[@PallaviRaj19]

Mam I am Pallavi Raj Thank you mam for this amazing session and make this theorem halwa theorem 😇😀😀 🔴HOMEWORK QUESTION🔴 Given - 🔺️PQR , A, B and C are mid points and PQ is 7 cm , QR is 8 cm and PR is 9 cm. To find - perimetre of 🔺️ABC ➡️ By MPT CB = 1/2QR = 4cm BA = 1/2PQ = 3.5cm AC = 1/2RP = 4.5cm Perimeter of 🔺️ABC = CB+BA+AC =4cm+3.5cm+4.5cm =12cm

[@sciencefacts3711]

IF PQ = 7CM THEN AB = PQ/2 Therefore AB = 3.5 QR = 8CM THEN CB = QR/2 THEREFORE CB = 4 PR = 9CM CA = PR/2 THEREFORE CA = 4.5 NOW PERIMETER OF ∆ABC = AB+BC+CA PERIMETER OF ∆ABC = 3.5+4+4.5 PERIMETER OF ∆ABC = 12CM

[@monalishanayak2113]

Mam please make a lecture on surface area and volume class 9th

[@shellve-v4s]

The answer of homework questions is 12 cm is the perimeter of triangle ABC Thankyou so much for explaining this theorem easily

[@prajktawadapurkar]

Good job

[@ujjwal8375]

Sh maan I live you as a student pls aap har video me padhaiye very very nice explaination

[@AjayPatil-eh2lc]

Mam wrote BE =CD in proof of converse MPT (I think by mistake)the right one is BE || CD,so don't get confuse.

[@Verstappen_betterthan_hamilton]

Yep you are right, it isn't equal but only parallel therefore it is not a parallelogram

[@Verstappen_betterthan_hamilton]

Ma'am didn't give full explanation, auctually since E is mid point of AB it mean AE = EB and since we already know that AE = CD (PROVED BY CPCT EARLIER) we can can EB is = DC and parallel therefore since one pair of sides is equal and parallel, we can say that Quad EBCD is a Parallelogram. I hope that clears any confusion.

[@RekhaKumari-yy1yf]

Hello mam I am Shagun Perimeter of triangle=a+b+c where a=4cm , b=3.5cm and c=4.5 cm That's why the perimeter will be 12cm ....….

[@harinarayanmeena9381]

Thank you mam this video is very helpful

[@SomaMishra-jw5cg]

Amazing Class ma'am

[@suganyav9219]

❤ amazing class mam

Can you make one shot of theoram on area

[@babysingha5127]

Ma'am aren't you teaching us in Class 10?

[@rambachanrambachan5433]

Very very very nice explanation 😊

[@nallathambid5707]

Thanks a lot mam

[@prathimadmello9602]

Yes😮😊😊😊😊

[@maafilms8448]

the perimeter or triangle abc equal 12

[@laxmibesoya8781]

Maam you are so cute ❤

[@SukhmanderSingh-dy2rx]

Mam pls teach class 10

[@gavya99]

Perimeter of Triangle ABC is 12cm Thank you ma'am video was really helpful

[@surajm344]

toooo lag tooo slow my teacher completed in 20min but u took 1hr omg , but u teach good

[@creatively349]

12 cm

Bhai vo. Mam h unhe to maaf kr do

[@Paswan-tnq]

Thik hai

Mam u are pretty and beautiful

[@Ayushi11325]

Given : PQ=7cm QR=8cm PR=9cm Since, PQ=7cm PC=CQ=3.5cm QR=8cm QA=AR=4cm PR=9cm PB=BR=4.5cm PC=AB PB=CA QA=CB In ∆ABC AB+CA+CB=Perimeter of ∆ 3.5+4.5+4=12cm Perimeter of ∆ ABC is 12 cm

[@nithinnithin9425]

HELLO MAM Pq=7cm Qr=8cm Pr=9cm Proof Cb=1/2qr(by midpoint theorem) Cb=1/2*8=4cm Ca =1/2pr Ca=1/2*9=4.5cm Ba=1/2pq Ba=1/2*7=3.5cm Perimeter of triangle abc 4+3.5+4.5=12 cm
