No. Angles don't have anything called a side length. However, one can use trigonometry to compute the angles of a triangle based on the side lengths of the triangle (triangles do have side lengths).
Because all side lengths are different, it must be a scalene triangle.
Only two equal side lengths
Yes and the given lengths would form an isosceles triangle.
That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
Given the lengths of two sides of a right triangle, you can find the length of the other side.
true
Yes, absolutely
If its a right angle triangle then its side lengths could be 3, 4 and 5

An isoceles triangle! It has two lengths the same!
Because all side lengths are different, it must be a scalene triangle.
A scalene triangle which has different side lengths
That number is called the "perimeter" of the triangle.
Only two equal side lengths
