State whether ∆ABC and ∆AED are congruent. Justify your answer.

Diagram will be in the comments.

I think that they are congruent since there are lines (I don't know what they are called exactly) intersecting certain lines (i.e. line segment AC and line segment AD, etc.) What do you call those lines?

Is there anything else that would signify that they are congruent? Or am I wrong, and they are in fact not congruent?

Answer 1

Diagram is not to scale.

Answer 2

yes ∆ABC and ∆AED are congruent because:
Reason1: BA=EA=7
Reason2: BC=ED
Reason3: AC=AD

Answer 3

Okay, thanks! :)
Is there a name for those lines that intersect at certain points? For instance the line that is intersecting line segment CD.

Answer 4

Not a special name for lines but if u consider ∆ACD then u can say that it is isosceles triangle
