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.
Doubling the side lengths of a triangle results in a perimeter that is also doubled. The perimeter of a triangle is the sum of its three side lengths, so if each side length is multiplied by two, the total perimeter will similarly be multiplied by two. For example, if a triangle has side lengths of 3, 4, and 5, its original perimeter is 12, and if the side lengths are doubled to 6, 8, and 10, the new perimeter will be 24.
That number is called the "perimeter" of the triangle.
Only two equal side lengths
