Answer

(i) In Δ ABC and Δ AMP,

⇒ ∠ABC = ∠AMP (Both = 90°)

⇒ ∠BAC = ∠MAP (Common angle)

∴ Δ ABC ∼ Δ AMP (By A.A. axiom)

Hence, proved that Δ ABC ~ Δ AMP.

(ii) We know that,

Ratio of corresponding sides in two similar triangles are proportional.

In Δ ABC and Δ AMP,

CAPA=BCMP\dfrac{CA}{PA} = \dfrac{BC}{MP}

Hence, proved that CAPA=BCMP\dfrac{CA}{PA} = \dfrac{BC}{MP}.
