 Hi and how are you all today? My name is Priyanka and the question says in figure 9.24 ABC and ABD are two triangles on same base AB. If line segment CD is bisected by AB at O, show that area of ABC is equal to area of ABD. Now this is the figure which we need to refer. Here we are given that ABC and ABD are on the same base AB and if line segment CD is bisected by AB at O, then show that area of AB is equal to area of ABD. Now here we are given that CO is equal to OD. Let us start with our solution. Area of AB is equal to area of AB. Now since we know that divides a triangle equal to area of ABD, now OB is the median. So therefore area of COB is equal to area of BOD. Let this be the second equation. Now on adding we have now area of CO is this. On adding COB to it the triangle will be ABC and similarly AOD plus BOD will give me this triangle. So I have over here area of COA CO plus area of COB area of AOD plus area of BO that is further equal to area of equals area of ABD. So this was the thing that was needed to be proved. I hope you enjoyed the session.
