Get below DAV Class 7 Chapter 9 Worksheet 2 Congruent Triangles Question and Answer.

1. In ∆ ABC and ∆ DEF, AB = DE and BC = EF (Fig. 9.19).

What additional information is required to make the two triangles congruent by SAS congruence condition?

2. ∆ABC is isosceles with AB = AC (Fig. 9.20).

Line segment AD bisects ∠A and meets the base BC at D. Find the third pair of corresponding parts which make ∆ADB = ∆ADC by SAS congruence condition. Is it true to say that BD = CD? Why?

3. In Fig. 9.21, AB II DC and AB = DC.

(i) Is ∠BAC = ∠DCA? Why?

(ii) Is ∆ABC = ∆CDA by SAS congruence condition?

(iii) State the three facts you have used to answer (ii).

4. In Fig. 9.22. which pairs of triangles are congruent by SAS congruence condition? If Congruent, write the congruence of the two triangles In symbolic form.

5. In Fig. 9.23. AB = AD end ∠BAC = ∠DAC.
