2:45:53 H.W- ∆LNQ Congruent to ∆MNR by RHS Angle Q = Angle R [CPCT] PQ=PR [Sides Opp. to equal angles] HENCE PROVED!!

[@coolvloggers3748]

thank you

[@KhushbooKumari-iq6bw]

2:19:43 hw ans ∆ ECB aur ∆ FBC ko congruent kara by SAS criteriA, BF=CF aaya then, ∆ABD aur ∆CBF ko congruent kara BY SAS , AD=CF aya THEN AD=CF=BE ho gya

[@AnupamJha-p6h]

Can you pls explain me how you proved ∆ABD OR ∆CBF

[@KhushbooKumari-iq6bw]

​@@AnupamJha-p6hABD aur CBF me AB=BC ( GIVEN HAI / TRIANGLE EQUILATERALHAI) AB=BF+AF (BF=AF BECAUSE CF MEDIAN H) =AB=2BF BC=BD+DC (SAME REASON) =BC=2BD AUR AB=BC (HAI TO WO VALUE PUT KARO ) 2BF=2BD => BF=BD ANGLE ABD = ANGLE CBF to issue 2 side aur included angle equal ho gya to SAS laga diya🙃

[@Studymotivator_2]

Vote for "Quadrilateral" ; "Circle' ❤👍🏻

[@sangitasharma2158]

42:28 Ans- given:- l is perpendicular bisector and P lies on line l. To prove:- AP=BP or P is equal distance from both point A and B PROOF:- In ∆ACP and ∆BCP angle ACP= angle BCP AC=BC PC=PC(common) Therefore, both are conruent (i cannot write in comment) By CPCT, AP=BP Thus, point p is equal distance from points A and B
