There are lots of formulae for triangles, depending on what exactly you want to calculate. Here is one, as an example:
perimeter = a + b + c
(where a, b, and c are the lengths of the three sides).
Depends on what formula.

The title of the formula is "Formula for the Area of a Triangle". No discrimination is expressed or implied.
no it has no sides that are the same * * * * * In mathematics, the word "normal" is used to mean perpendicular (or at right angles). In that context, a scalene triangle will be a normal, or right angled triangle if its angles are (90, A and 90-A) degrees where 0<A<90. If by "normal" you mean "ordinary" or "nothing special about it" then the answer is yes.
a plane triangle is a normal triangle, like the isosceles, right angled, equilateral and scalene triangle.
The formula which defines a triangle is: Number of vertices = 3.
right triangle
to find the area of any triangle follow the formula: 1/2(b*h) "B" - stands for the base of the triangle "H" - stands for the height of the triangle
There is no specific formula for the base of a triangle. More often than not, it is to measure it.Otherwise, the answer depends on what information you do have.
Heron created a formula to find the area of any triangle given three side lengths. It is known as Heron's Formula.
The formula to calculate the area of a triangle is A = 1/2 * base * height, where A represents the area, the base is the length of the triangle's base, and the height is the perpendicular distance from the base to the opposite vertex. This formula is derived from the fact that the area of a triangle is half the product of its base and height. By plugging in the values for the base and height into the formula, you can easily determine the area of the triangle.
there should be 3 angles in a normal triangle......
