Question

construct a triangle ABC in which ab is equal to 6 cm and angle B equal to 40 degree angle c equal to 110 degree
​

Answer 1

Explanation:

Steps:

1. Draw a line AB of length 6 cm.

2. Make an angle of 30

∘

at A and extend the line from A making this angle.

3. Make an angle of 60

∘

at B and extend the line from B making this angle till it meets the line from step 2 at point C.

Hence, we got the △ABC

Now,

4. Extend the line AB to B

=8 cm.

5. Make an angle of 60
