Steps: 1 Mark
Construction: 1 Mark
Draw a line segment AB = 3 m and extend it.
Sum of two interior opposite angles is equal to the exterior angle.
∠BAC+∠ACB=120∘
Hence, ∠ABC=60∘
Hence, the given triangle is an equilateral triangle.
Draw AB = 3 m
Draw a line AC of length 3 m making an angle of 60 degrees with AB. Join BC.
