triangle PQR~ triangle LTR. In triangle PQR,PQ=4.2 cm, QR=5.4 cm, PR=4.8 cm. Construct triangle PQR " and " triangle LTR, such that (PQ)/(LT)=(3)/(4).

Answer»


Answer :If seg QR is divided into 3 equal parts, then TR will be 4 times each part of seg QR.
So, if we construct `triangle PQR`, point T will be on side RQ, at a distance equal to 4 parts from R.
Now, point L is the point of intersection of RAY RP and a line through T, parallel to PQ.
`triangle LTR` is the required triangle SIMILAR to `triangle PQR`.
