If ←→AD||←→BC, then area (ΔABC) = area (ΔBEC). = area (ΔDBC) State true or false
True
If ←→AD||←→BC, then area (ΔABC) = area (ΔBEC) = area (ΔDBC). This is because base length of all the triangles is the same and heights are also equal since they lie between same parallel lines. This is generally stated as
Two or more triangles having a common base and lying between same parallel lines will have equal areas.
