 Hello and welcome to the session. In this session we will learn about construction of a triangle when three of its angles and the included side are given. Now suppose we have to construct triangle ABC where angle A, angle B and the side included in between these two angles that is the side AB are given. Now we will start with the steps of construction. Now in the first step draw the given side AB. So here we have drawn the given side AB. Now in the second step add A, draw an angle AB which is equal to the given angle A. So here add A we have drawn an angle XAB which is equal to the given angle A. Now in the next step add B, draw an angle YBA which is equal to the given angle B. So here we have drawn an angle YBA at the point B which is equal to the given angle B. Now in the fourth step add the way XA and YB intersect at C. So we will name this point of intersection of these ways as C and the triangle ABC is the required triangle. So let us name the point of intersection of these ways as C and hence triangle ABC is the required triangle. Now let us discuss an example for this. Here we have to construct a triangle QR in which Q is equal to 5 centimeters is equal to 45 degrees and angle Q is equal to 30 degrees. So in this example the two angles and the sides included in between these angles are given. Now we will start with the steps of construction. In the first step draw a line segment PQ is equal to 5 centimeters. So we have drawn a line segment PQ is equal to 5 centimeters. Now in the second step HB draw an angle XPQ is equal to 45 degrees. So we have drawn an angle XPQ is equal to 45 degrees. Now in the next step HQ draw an angle YTB is equal to 30 degrees. So we have drawn an angle YQB is equal to 30 degrees. Now in the next step let the ways XP and YQ intersect at R. So let us name this point of intersection of the ways YQ and XP as R. Is the required triangle. So here you can see that the triangle PQR is the required triangle in which angle P is equal to 45 degrees, angle Q is equal to 30 degrees and the sides of PQ is equal to 5 centimeters. So in this session you have learnt about construction of a triangle when two of its angles and the included sides are given. And this concludes our session. Hope you all have enjoyed the session.
