3.9 cm

2. In figure, ABCD is a quadrilateral in which AB = BC and AD = DC. Measure of ∠BCD is:
105°
125°
85°
100°

3. In the adjoining figure, △ABC ≅ △ADC. If ∠BAC = 30∘ and ∠ABC = 100∘ then ∠ACD is equal to

50°
80°
60°
76°

4. It is not possible to construct a triangle when the lengths of its sides are

120° and 190°
50° and 70°

6. In △ABC and △DEF, AB = DE and ∠A = ∠D.Then two triangles will be congruent by SA axiom if:
BC = DE
AC = EF
AC = DE
none of these

7. D is a Point on the Side BC of a △ABC such that AD bisects ∠BAC then:
CD = CA
CD > CA
BA > BD
BD = CD

8. In the adjoining figure, O is Mid – point of AB. If ∠ACO = ∠BDO, then ∠OAC is equal to

∠OBD
∠ODB
∠DBO
∠OCA

9. In the adjoining fig, AD = BC and ∠BAD = ∠ABC. If ∠BAD = 120∘ and ∠ABD = 35∘, then ∠CAD is
