Angle 1 = 30°

Angle 2 = 90°

⇒ Angle 3 = 60°

So, it's right triangle. We can set the length of one side and get all other sides.

So, we have 1 triangle. If there are 2 or more triangles with the same data, all the triangles will be congruent because of : Two triangles are congruent if " ASA: Two interior angles and the included side in a triangle have the same measure and length, respectively, as those in the other triangle."
