Question

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

Answer 1

Answer:

Step-by-step explanation:

(i) AB = 7 cm, AC = 6.5 cm and angle A = 120°.

Step 1 : Draw line segment AB = 7 cm using ruler

Step 2 : Draw an angle of 120° at A using Protector

Step 3 : Take length of 6.5 cm at angle drawn and mark point C

Step 4 : Join AC  & BC

(ii) BC = 8 cm, AC = 6 cm and angle C = 40°.

Step 1 : Draw line segment BC = 8 cm using ruler

Step 2 : Draw an angle of 40° at C using Protector

Step 3 : Take length of 6 cm at angle drawn and mark point A

Step 4 : Join AC  & AB

(iii) An isosceles obtuse triangle with equal sides 5 cm​

Step 1 : Draw a line segment = 5 cm

Step 2 Draw any angle between 90° & 180° using protector

Step 3 Take a length of 5 cm at angle Drawn

Step 4 : Join the point with points of line segment Drawn first
