Can you use the SSS Postulate or the SAS Postulate to prove triangle ABC and triangle AED are congruent?

From the diagram given,

when you have two triangles like this:

The crossing strokes on AB and PR indicate that both lines are the same in length.

i.e. AB = PR

When you have tiny arcs like we see in

With this information, we can therefore solve the question.

From the question,

AC = AD (single stroke lines)

BC = DE (double stroke lines)

Now there is a theorem that states that "When two sides of a triangle are equal to two sides of another triangle, then the third side of both triangles are necessarily equal"

Therefore, we can conclude that

AB = AE

Thus, the 3 sides of both triangles are equal. Thus SSS is a solution.

Now we can also see that both triangles have the same arc at

Thus, As such, we can also conclude that since angle is equal and we know at least 2 sides are equal, then

SAS is another solution.

Thus the final answer is: Both Apply
