From the diagram, what can you conclude about CAD? A.) it’s an isosceles triangle B.) it’s an equilateral triangle C.) it’s an obtuse triangle D.) it’s an equiangular triangle
Accepted Solution
A:
A) it is an isosceles triangle.
Using ASA, we know that ΔABC and ΔADE are congruent. This means that side CA = DA. Since there are two equivalent sides, it is isosceles.
