We will be happy to post videos as per your requirements also. Do write to us.Here we will discuss some theorems on chord and subtended angle.
|1) OL ⊥ AB ⇒ AL = 1/2AB||1) OM ⊥ CD ⇒ CM = 1/2CD|
|2) AB = CD||2) Given|
|3) 1/2 AB = 1/2 CD||3) Given|
|4) AL = CM||4) From AB = CD|
|5) OA = OC||5) Equal radius of the circle|
|6) AL = CM||6) From (4 )|
|7) ∠ALO = ∠CMO||7) Each 900|
|8) OL = OM||8) CPCTC|
|1) AB = CD||1) Given|
|2) OA = OC||2) Radius of same circle|
|3) OB = OD||3) Radius of same circle|
|4) ΔAOB = ΔCOD||4) SSS Postulate|
|5) ∠AOB = ∠COD||5) CPCTC|
|1) ∠POQ = 2∠PRQ||1) Given|
|2) ∠POQ = 2∠PSQ||2) Given|
|3) 2∠PRQ = 2∠PSQ||3) From (1) and (2)|
|4) ∴ ∠PRQ = ∠PSQ||4) From (3)|
|5) Reflex ∠POQ = 2∠PRQ and Reflex ∠POQ = 2∠PSQ||5) From the diagram|
|6) 2∠PRQ = 2∠PSQ||6) From the diagram|
|7) ∠PRQ = ∠PSQ||7) From (6)|
