The Theorem of Pythagoras.
They are of the same lengths
Relationship between the lengths and the measures of angles are related to theorems like the opposite side of the largest angle is the largest side two equal angles oppositee sides are also equal
Heron created a formula to find the area of any triangle given three side lengths. It is known as Heron's Formula.
The perimeter formula of a triangle is the sum of the lengths of all three sides. Mathematically, it can be expressed as P = a + b + c, where P is the perimeter and a, b, and c are the lengths of the three sides of the triangle.
The Pythagorean Theorem is not a triangle. It's a statement that describes a relationship among the lengths of the sides in any right triangle.

The formula of the hypotenuse (the longest side of the triangle) is the other two lengths squared and added together.

The perimeter formula of a triangle is the sum of the lengths of all three sides. Mathematically, it can be expressed as P = a + b + c, where P is the perimeter and a, b, and c are the lengths of the three sides of the triangle.
the angle between the two sides is used in the formula A = 1/2 a*b*sin(C) where A is area, a and b are side lengths, and C is the angle between sides. Simply use algebra to rearrange the formula to solve for C.
Area = 1/2*a*b*SineC where a and b are the lengths and C is the angle between them. The above formula holds true for any triangle.
Using the cosine formula the angle between lengths 8 and 12 is 55.77113367 degrees. Using the sine formula the area of the triangle is 39.68626966 or about 40 square units.
A scalene triangle has 3 sides of different lengths An isosceles triangle has 2 sides of equal lengths An equilateral triangle has 3 sides of equal lengths
you can use the sine, cosine, tangent formula.
Add the lengths of each side together to get the perimeter.
