Mam easy trick to find angles in parallel lines is 1. Corresponding angles - F 2. Alternative angles - Z 3. Co-interior angle - C

[@saniyahamid1189]

Thanku maam for this session❤❤ I got 27/30 Homework: PQ||ST Angle PQR=110* Angle RST=130* Prove=angle QRS=? Construction:draw a line MN through point R||ST Therefore MN||pQ Proof: Angle TSR+angle SRN=180(angles on the same side of Transvarsal are supplementry ) 130+angle SRN#=180 Angle SRN=50* PQ||MN Therefore angle PQR=angle QRN(alt۔interiorangles) 110*=angle QRS+angle SRN 110*=angle QRS+50* 110*-50*=angel QRS 60*=angle QRS

Thank You So Much Mam for the Session. It was really amazing😄❣💫 🔺HOMEWORK ANSWER🔻 Construct a line A || ST Now- ∠SRA + ∠TSR = 180° (Co interior angles) ∠SRA + 130° = 180° ∠SRA = 50° ∠PQR = ∠QRA (Alternate Interior Angles) 110°= ∠QRA ∠QRA = ∠QRS + ∠ SRA (Given) 110° = ∠QRS + 50° ====> ∠QRS = 60° My Score was 29/30😊

[@TheRealAbhimanyu]

Thank 🙏🙂 You so much mam, it was a Amazing 😍 Session, i really enjoyed it . Lines and Angles is one of the my favorite 😍 Chapter. By the way i got 26/30( Due to silly mistake in 2nd last question 😝 Although i knew the answer 😅) Homework :- By Constructing a line (AB) such that parallel to PQ and ST and passes through R , Then by Co interior angles ARQ =70° and similarly by co interior angels BRS = 50° Then angles ARQ+ QRS+SRB=180° 70+QRS +50=180° (Form a line) So angle QRS = 60° ans Thank 🙏 you so much mam once again.🙂

[@anupamasharma9941]

Ma'am, this session really helped me to get all my concepts Clear . I scored 28/30 Homework answer- PQ ll ST PQR = 110 RST = 130 PQR + QRX = 180 110 + QRX = 180 Hence, QRX = 70 RST + SRY = 180 SRY = 180 - 130 SRY = 50 ( straight line) QRX + QRS + SRY = 180 70 + QRS + 50 = 180 QRS + 120 = 180 QRS = 180 - 120 Therefore, QRS = 60

[@PoojaYadav-cv1iy]

Homework question (Ansh) , Given: PQ || ST , RST =130, PQR 110 Find: QRS Construct: line R TO E (right side) let extent angle R to E so , TSR +SRE = 180 (CO-INTEROR) 130 + X = 180 X = 50 NOW, POR = QRE (ALTERNATE INTERIOR ANGLE) 110 = QRE SO, QRE - SRE = QRS 110-50 = QRS 60 = QRS answer

Homework Problem Answer:- Since PQ || ST [Given] and EF || ST [Construction] ∴ PQ || EF and QR is a transversal ⇒ ∠PQR = ∠QRF [Alternate interior angles] But ∠PQR = 110° [Given] ∴∠QRF = ∠QRS + ∠SRF = 110° …(1) Again ST || EF and RS is a transversal ∴ ∠RST + ∠SRF = 180° [Co-interior angles] or 130° + ∠SRF = 180° ⇒ ∠SRF = 180° - 130° = 50° Now, from (1), we have ∠QRS + 50° = 110° ⇒ ∠QRS = 110° - 50° = 60° Thus, ∠QRS = 60° Mam I scored 30/30
