There are many formulae for triangles:
Some formulae will calculate sides given angles or conversely.
Some will calculate the area.
It is not possible to say how you would use a formula without knowing what it is for!
Use the formula 1/2 the base * the height
hypotenuse
That is it. Just the hypotenuse - provided you have the correct triangle.
right triangle
To find the vertical distance (or height) of a triangle, you can use the formula for the area of a triangle: Area = 1/2 × base × height. If you know the area and the length of the base, you can rearrange the formula to solve for height: height = (2 × Area) / base. Alternatively, if you have the coordinates of the triangle's vertices, you can use the formula for the area based on those coordinates to find the height.
Use the formula 1/2 the base * the height
Use Heron's Formula
The hypotenuse

Its hypotenuse
That is it. Just the hypotenuse - provided you have the correct triangle.
right triangle
The formula for the area of a triangle is A = ½bh. We can use this formula to find the height, h, of the triangle: 16 = ½*4*h 16=2h /2 /2 8=h The height of the triangle is 8 units.
Use the distance formula to calculate the distances between the three vertices. If they are all different, the triangle is scalene, if only two are the same, the triangle is isosceles, and if they are all the same, the triangle is equilateral.
To find the vertical distance (or height) of a triangle, you can use the formula for the area of a triangle: Area = 1/2 × base × height.

Alternatively, if you have the coordinates of the triangle's vertices, you can use the formula for the area based on those coordinates to find the height.
This depends what you are trying to work out, and what kind of triangle you have.
