Construct a triangle ABC in which BC is 6 cm, ∠ B is 70∘ and AC - AB = 2.
Steps-
-Draw line segment BC=6 cm. Draw ray BX which makes an angle 70∘ with BC.
-Cut line segment BD of length AC-AB=2 cm on BX on the opposite side of BC, Join CD.
-Draw the perpendicular bisector of CD. Let the perpendicular bisector intersect ray BX at A.
-Angle ABC is the required triangle.
