Δ ODC ~ Δ OBA, ∠ BOC = 125°
and ∠ CDO = 70°. Find ∠ DOC, ∠ DCO and
∠ OAB.
3. Diagonals AC and BD of a trapezium ABCD
with AB || DC intersect each other at the
point O. Using a similarity criterion for two
triangles, show that OA/ OB= OC/ OD, QR QT
QS PR  and ∠ 1 = ∠ 2. Show
that Δ PQS ~ Δ TQR.
5. S and T are points on sides PR and QR of
Δ PQR such that ∠ P = ∠ RTS. Show that
Δ RPQ ~ Δ RTS.
6. In Fig. 6.37, if Δ ABE ≅ Δ ACD, show that
Δ ADE ~ Δ ABC.
