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). **

**Answer 1:**

**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? **

**Answer 2:**

**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).**

**Answer 3:**
