In Δ ABC and ΔPQR, in a one to one correspondence then

Δ ABC and ΔDEF are equilateral triangles. If A(ΔABC) : A(ΔDEF) = 1 : 2 and AB = 4, find DE.

In figure 1.66, seg PQ || seg DE, A(Δ PQF) = 20 units, PF = 2 DP, then find A(DPQE) by completing the following activity.

A(Δ PQF) = 20 units, PF = 2 DP, Let us assume DP = x. ∴ PF = 2x

In Δ FDE and Δ FPQ,

∠FDE ≅ ∠ .......... corresponding angles

∠FED ≅ ∠ ......... corresponding angles

∴ Δ FDE ~ Δ FPQ .......... AA test
