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.

How about 3, 4 and 5 or 6, 8 and 10 in fact any of a Pythagorean triplets will are possible.
the sum of any two sides should be GREATER than the third side. (ex. 5, 6, 9. is it possible? well, 5+6=11, 11>9: YES; 6+9=15, 15>5: YES; 5+9=14, 14>6: YES. so yes it would make a triangle) :)
A square.
To find the perimeter of a triangle, you need to add the lengths of all three sides. If two sides of the triangle are 6 and 5 units long, you still need to know the length of the third side to find the perimeter. Without the length of the third side, it is not possible to calculate the perimeter of the triangle.
Area of the triangle: 0.5*6*5 = 15 square units
Yes they can. Where the shortest sides added together are greater than the longest side, a triangle is formed.
The coordinates are the vertices of a triangle since they form three points.
