 Hello and welcome to this session. In this session, we shall learn about the construction of a triangle when two of its sides and the included angle are given. Now suppose triangle ABC has to be constructed in which sides AB, BC and the included angle B are given. Now for this, we will start with the steps of construction. Now the first step is of the two given line segments, we have drawn a line segment BC. Now in the second step we construct and making an angle the given angle B. So we have constructed an angle XPC which is equal to the given angle B. Now in the first step segment of the given measure. So here we are obtaining a point ABX such that AB is the line segment of the given measure. Now in the next step, join AC and triangle ABC is the required triangle. So on joining AC, we are getting a triangle ABC which is the required triangle. An example is to construct a triangle ABC with is equal to 4.3 cm, BC is equal to 3.4 cm and then B is equal to 60 degrees. So this is the example in which and the included angle of a triangle. Now let us start with the steps of construction. In the first step line segment BC is equal to 3.4 cm. We have drawn a line segment BC of 3.4 cm. BC 60 degrees is equal to 60 degrees in segment of length. So we are obtaining a point A 4.3 cm. Now in the fourth step and then the triangle the required triangle. So we have joined AC for ABC is the required triangle. We have learnt the construction triangle when the length of two sides and the included angle are given. And this completes our session. Hope you all have enjoyed the session.
