Equilateral triangles
Yes when two lines share a common end point an angle is formed
All right angle triangles have a 90 degree angle and two acute angles which all together the 3 angles add up to 180 degrees.
Two triangles are congruent when they have the same shape and size, meaning all corresponding sides and angles are equal. The most common criteria for establishing congruence are Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), Angle-Angle-Side (AAS), and Hypotenuse-Leg (HL) for right triangles. If any of these conditions are met, the triangles can be considered congruent.
To determine which overlapping triangles are congruent by the Angle-Side-Angle (ASA) postulate, you need to identify two angles and the included side of one triangle that correspond to two angles and the included side of another triangle. If both triangles share a side and have two pairs of equal angles, then they are congruent by ASA. For a specific example, if triangles ABC and DEF share side BC and have ∠A = ∠D and ∠B = ∠E, then triangles ABC and DEF are congruent by ASA.
intersection
Two adjacent angles that share a common side are said to be contiguous. Two triangles next to each other would be an example of a contiguous angle, or a figure that resembles . The line in the middle is shared by both triangles.

adjacent angle
Yes.
Not so. The two acute angles of a right triangle must add up to 90 degrees.So if the triangles have one congruent acute angle in common, they must alsohave the other acute angle in common, and then they're similar.

Ensure the common angle is not between the two common sides and is not a right angle. That is, if the triangles are ABC and DEF then make angle CAB = FDE; and sides AB = DE and BC = EF (make AB > BC and thus DE > EF) Then you will be able to draw two non-congruent triangles by making AC not equal to DF. (If you make AC less than BC, then DF will be greater than DE).
