1. Observe the figure and find the value of
ㄥA + ㄥN + ㄥG + ㄥL + ㄥE + ㄥS.

2. If the three angles of a triangle are in the ratio 3: 5: 4, then find them.

3. In ΔABC, if ㄥB is 3 times ㄥA and ㄥC is 2 times ㄥA, then find the angles.

4. In ΔLMN, MN is extended to O. If ㄥMLN = 100 – x, ㄥLMN = 2x and ㄥLNO = 6x – 5, find the value of x.

5. Given that ΔABC ≅ ΔDEF (i) List all the corresponding congruent sides (ii) List all the corresponding congruent angles.

6. If the given two triangles are congruent, then identify all the corresponding sides and also write the congruent angles.

7. If the given triangles ΔABC and ΔEFG are congruent, determine whether the given pair of sides and angles are corresponding sides or corresponding angles or not.
ㄥB and ㄥE

9. State whether the two triangles are congruent or not. Justify your answer.

10. II. Construct a triangle ABC with given conditions.
(i) AB = 7 cm, AC = 6.5 cm and∠A = 120°.
(ii) BC = 8 cm, AC = 6 cm and ∠C = 40°.
(iii) An isosceles obtuse triangle with equal sides 5 cm

11. If ΔMNO ≅ ΔDEF, ㄥM = 60and ㄥE = 450 then find the value of ㄥO.

12. Using the given figure, prove that the triangles are congruent. Can you conclude that AC is parallel to DE.

13. In the given figure find the values of x and y.

14. In ΔDEF, ㄥF = 480, ㄥE = 680 and bisector of ㄥD meets FE at G. Find ㄥFGD.

15. From the given figure find the value of y
