 Hi and welcome to the session. Let us discuss the following question. Question says, construct the following quadrilateral. You are required to construct rhombus BESD in which B is equal to 4.5 cm and Et is equal to 6 cm. Let us now start with the solution. Now first of all, we will draw a rough sketch of rhombus BESD. Now clearly you can see this is a rough sketch of rhombus BESD and we are given that Be is equal to 4.5 cm, Et is equal to 6 cm. Now recall that rhombus is a quadrilateral with sides of equal length so each side of rhombus BESD measures 4.5 cm as each of its sides is equal to Be which is further equal to 4.5 cm. Let us now start with the construction. Now first step of construction is draw Et equal to 6 cm. Now clearly you can see here we have drawn Et equal to 6 cm. Now to construct rhombus BESD we are required to construct two triangles, triangle Est and triangle Et. And note that both the triangles triangle Est and triangle Et have the same base Et and both of them lie on opposite sides of base Et. Now second step of construction is with ER centre draw two arcs of radius 4.5 cm on opposite sides of Et. Note that Est and Eb both are equal to 4.5 cm so we will mark two arcs of radius 4.5 cm with ER centre to locate point S and point B. Clearly you can see we have drawn these two arcs of radius 4.5 cm with ER centre. Now next step of construction is with ER centre draw two arcs of radius 4.5 cm each to intersect the previous arcs at points S and B. Clearly you can see TS and TB both are equal to 4.5 cm so we will draw two arcs of 4.5 cm to intersect the previous arcs at points S and B. Clearly you can see we have drawn two arcs of radius 4.5 cm each from centre T. Now this point is point S and this point is point B. Now to obtain rhombus BEST we need to join BE, ES, ST and TB. So our last step of construction is join BE, ES, ST and TB. Now clearly you can see we have joined BE, ES, ST and TB. So BE, ST is the required rhombus where ET is equal to 6 cm, BE is equal to 4.5 cm, ES is equal to 4.5 cm, TS is equal to 4.5 cm and BT is equal to 4.5 cm. So this is our required construction. This completes the session. Hope you understood the solution. Take care and have a nice day.
