Yes.
Form a triangle with the six coins. Now you have 3 rows with 3 coins in each row!
A scalene has three sides of unequal lengths, and all threes angles different.The largest angle defines the triangle¹:acute: a scalene triangle could have sides 6, 9, 10right angle: a scalene triangle could have sides 6, 8, 10obtuse: a scalene triangle could have sides 6, 7, 10So a scalene triangle could be any of acute, right angle or obtuse.¹In terms of acute, right angle or obtuse. Triangles can also be defined in terms of their sides: equilateral (all three sides equal), isosceles (two sides equals) or scalene (no sides equal)

Yes.
No. To form a triangle the sum of the shorter two sides MUST be greater than the longer side. 6 + 5 = 11 < 12 → cannot be a triangle.
A square.
The sum of the 2 shorter sides must be greater than the longest side to form a triangle
A Triangle.
Yes.
Yes.
Yes, it's possible.
12 of then but if they are joined together in the form of a 6 sided hexagon then 6 endpoints are needed.
Yes, two sides of the triangle have to add up to more than the third side
