HELP PLEASE! From the diagram, what can you conclude about Triangle CAD? It is an obtuse triangle. It is an equiangular triangle. It is an equilateral triangle. It is an isosceles triangle.

    triangles CBA and DEA are congruent (by 2 angles and the corresponding side) So what can you say about the lines CA and DA?

    well because the 2 triangles are congruent then CA and DA are congruent

    we know nothing about how DC is related to AD and DC so isosceles is the correct answer
