I'm not sure what you are asking, so I may not be answering your question, but I'll try to the best of my ability.
This is only for RIGHT TRIANGLES
*Another way to find the other side beside the shortcut is by using the Pythagorean Theorum (a2+b2=c2) if you are given the other two side measurements.*
To find the altitude or height of an equilateral triangle, take one-half of the length of a side of the triangle and multiple by "square root" of 3. So, if for example, the side has length 10, the height = 5 Square root of 3.
2.08cm. To find the area of any triangle - divide the length of the base by 2, then multiply the result by the height.
Base = 8, Height = 15
By using Pythagoras' theorem.
Use Pythagoras to find the perpendicular height of the triangle: 132-52 = 144 and the square root of this is the height of the triangle which is 12 cm Area = 1/2*12*10 = 60 square cm
Are of a triangle is (length of the base) times (height)/2 .
By measuring it
The measurement of the angle of the triangle...supposing it is a triangle.

You cannot calculate the height of a triangle from just the length of two sides. You would either have to measure it or obtain additional information about the triangle.
The square of the length of the base plus the square of the length of the height will equal the square of the length of the hypotenuse of your right triangle, per Pythagoras. Square the hypotenuse, subtract the square of the height, and then find the positive square root of that and you'll have the base of your right triangle.
The area of the triangle in square meters is (1/2 the length of the triangle's base, in meters) times (the length of the triangle's height, in meters).
altitude(height)=(Area * 2) /length(Base)
The area of any triangle is (1/2 the length of its base) x (its height).
The triangle only has one height, not two. The height is NOT the length of the other two sides, besides the one it's sitting on. The height is exactly that: the height. It's how high the ceiling has to be if you want to stand that triangle up in a room. In general, the height is LESS than the length of either side that the triangle is not sitting on.
It varies depending on the triangle.
