Question

∆PQR is similar to ∆ABC, PQ=3 cm, QR=4 cm, PR=5 cm. A(∆PQR):A(∆ABC)=1:4. Construct both the triangles.
​

Answer 1

Answer:

the decomposition or separation of molecules by the action of light.

Answer 2

Answer:

steps of construction:

1. draw a line PR of 5cm.
2. make a arc of 3 cm from point P and make an arc of 4 cm from point R.
3. join PQ and QR. and traingle PQR is formed.
4. make an acute angle just below PR at point P and name as PX.
5. make point on PX such that P1=P2=P3=P4.
6. join P4 to R.
7. make P1B ll to P4R.
8. make BA ll to PQ.
9. therefore the traingles are drawn.
