Question

construct a triangle in which ab is equal to 5 cm angle BAC is equal to 60 degree and AC is equal to 7 cm find BC​

Answer 1

First draw base ab = 5cm

then on vertex b keep Protacter and measure 60°.

after measuring draw a ray from bto the the point of 60° you marked .

then in compass take 3 cm distance and then keep it metal point on b and draw arc on the ray you draw .

then join a vertex and the arc .

you will get the triangle.
