Question

ln triangle pqr s and t are points on sides pq and pr respectively if triangle qsr=qtr show that angle ost=angle orq

Answer 1

if triangle qsr=qtr ,then their area would be also equal and they lie on same base qr and their area are also equal so st will be parallel to qr and sr will be a transversal and angle ost will become equal to angle orq (alternate interior angles).
