 Hello and welcome to the session. In this session we will discuss the following question and the question says, Constructor Triangle ABC with AB is equal to 6 cm, BC is equal to 4 cm and angle B is equal to 60 degrees. So we have to construct a triangle in which the length of two sides and the included angle is given to us. Let's start the solution now. We are given that BC is equal to 4 cm. So first we will construct BC. Step one of construction is draw a line segment BC which is equal to 4 cm. So we have drawn a line segment BC of length 4 cm. It is also given to us that angle B is equal to 60 degrees. So now we will construct an angle of 60 degrees at B. Step two is at B construct angle CBD which is equal to 60 degrees. So now we will construct an angle of 60 degrees at B. We have constructed this angle CBD at B which measures 60 degrees. We are given that AB is equal to 6 cm. So in step 3 we will construct AB. Step three is with B as center and radius equal to 6 cm, draw an arc to cut BD at A. So with B as center and radius equal to 6 cm, we draw this arc and this point where this arc cuts BD is the point A. Now step four is join AC. So we will now join the points A and C. Thus we have constructed triangle ABC in which BC is equal to 4 cm, AB is equal to 6 cm and angle B is equal to 60 degrees. Therefore triangle ABC is the required triangle. With this we end our sessions. Hope you enjoyed the session.
