In figure, if D = C, then it is true that ∆ADE ∆ACB? Why?


(True)

In ∆ADE and ∆ACB,


Given,


D = C


A = A [common angle]


As we know sum of all the angles of a triangle is equals to 180.


So, by angle sum property of triangle the third angle of both triangles must be equal.


E = B


∆ADE ACB [by AAA similarity criterion]
