Answer 1

$\huge\red{\boxed{\mathscr{SᴏʟᴜTɪᴏɴ ↓}}}$

• Draw a line AB of length 6 cm.

• Draw a line AB of length 6 cm.Make an angle of 30∘ at A and extend the line from A making this angle.

• 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

• Extend the line AB to B′, such that AB′=8 cm.

• 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 △AB′C′
