Question

in triangle PQR, E and F are points on the sides of PQ and PR respectively. PQ=1.28cm,PR=2.56cm,PE=1.8cm amd PF=3.6cm. State whether EF//QR or not?
$delta =under root s(s - a)(s - b))(s - c)$
​

Answer 1

Answer:

Answer: In ΔPQR, E and F are two points on side PQ and PR respectively. Hence, EF is not parallel to QR. Hence, EF is parallel to QR.

Answer 2

Step-by-step explanation:

in triangle PQR, E and F are points on the sides of PQ and PR respectively. PQ=1.28cm,PR=2.56cm,PE=1.8cm amd PF=3.6cm. State whether EF//QR or not?

delta =under root s(s - a)(s - b))(s - c)delta=underroots(s−a)(s−b))(s−c)
