Question
In the following, write the correct answer.
In $\triangle\text{ABC}$ and $\triangle\text{DEF},$ if AB = AC, $\angle\text{A}=\angle\text{D}.$ The two triangles are:
✓

Answer

  1. AC = DE
    Solution:
    In $\triangle\text{ABC},$
    AB = DF
    $\angle\text{A}=\angle\text{D}$
    We know that, two triangles will be congruent by ASA rule, if two angles and the included side of one triangle are equal to the two angles and the included side of other triangle.
    AC = DE.
