triangle
​

Answer 1

Answer:

Steps for construction:

1. draw BC 7 cm.
2. taking B as centre draw an angle of 70° and taking C as centre draw an angle of 60°.
3. From B draw a line exceeding downwards of any angle.
4. From B draw arc with help of compass of any length on the downward line.draw the same for arc next and mark them as B1 , B2, B3, B4.
5. From B4 join to C.
6. From B3 join to BC taking same measure of B4.and mark it as C' .
7. Then from C' draw a line to AB taking same measure of C . and mark it as A' .

Hence, A'BC' is the required triangle.
