Question

5. In adjoining figure PQ perpendicular BC,
AD perpendicular BC then find following ratios.
(i)
Α(ΔΡΟΒ)/A(ΔPBC)
А (ΔРВС)/А(ΔАВС)
A (ΔABC)/ A(Δ ADC)
A(ΔADC) / A(ΔPQC)​

Answer 1

Answer:

(i)A(△PQB)/A(△PBC)

=PQ×BQ/PQ×BC

=BQ/BC

(ii)A(△PBC)/A(△ABC)

=PQ×BC/AD×BC

=PQ/AD

(iii)A(△ABC)/A(△ADC)

=AD×BC/AD×DC

=BC/DC

(iv)A(△ADC)/A(△PQC)

=AD×DC/PQ×QC
