Answers
Step-by-step explanation:
Given: seg AB || seg PQ , seg AB ≅ seg PQ, seg AC || seg PR, seg AC ≅ seg PR To prove: seg BC || seg QR, seg BC ≅ seg QR Proof: Consider ABQP, seg AB || seg PQ [Given] seg AB ≅ seg PQ [Given] ∴ ABQP is a parallelogram. [A quadrilateral is a parallelogram if a pair of its opposite sides is parallel and congruent] ∴ seg AP || seg BQ …..(i) ∴ seg AP ≅ seg BQ …..(ii) [Opposite sides of a parallelogram] Consider ACRP, seg AC || seg PR [Given] seg AC ≅ seg PR [Given] ∴ ACRP is a parallelogram. [A quadrilateral is a parallelogram if a pair of its opposite sides is parallel and congruent] ∴ seg AP || seg CR …(iii) ∴ seg AP ≅ seg CR …….(iv) [Opposite sides of a parallelogram] Consider BCRQ, seg BQ || seg CR seg BQ ≅ seg CR ∴ BCRQ is a parallelogram. [A quadrilateral is a parallelogram if a pair of its opposite sides is parallel and congruent] ∴ seg BC || seg QR ∴ seg BC ≅ seg QR [Opposite sides of a parallelogram]Read more on Sarthaks.com - https://www.sarthaks.com/850467/in-the-adjoining-figure-if-seg-ab-seg-pq-seg-ab-seg-pq-seg-ac-seg-pr-seg-ac-seg-pr-then-prove-that
