That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.
An acute triangle sometimes known as a scalene triangle has 3 different side lengths and 3 different interior acute angles that add up to 180 degrees
If its a right angle triangle then its side lengths could be 3, 4 and 5
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).
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
A scalene triangle
