Question

In a triangle PQR if S and T are the midpoints of the sides PQ and PR respectively, then prove that the line segment ST is parallel to QR and ST = ½QR

Answer 1

Answer:

ST is parallel to QR (since ST is mid-point of PQ and PR) by proportionality theorem

PQPS=QRST⇒PS+PSPS=QRST⇒21=QRST⇒QR=2×ST⇒2×6.2⇒12.4.
