You can use the midpoint formula, if you know all of the vertexes' coordinates.
For example, say you have an equilateral triangle with vertexes at points (0,0), (4,0), and (2,sqrt12). I'll choose (2,sqrt12) as my base of operations. (sqrt is the shortened form of "square root of")
First, I find the midpoint between (0,0) and (4,0), which is (2,0).
Next, I find the midpoint of (2,0) and (2,sqrt12). The midpoint formula is ((x1 + x2)/2, (y1 + y2)/2). Just plug in the numbers: ((2 + 2)/2, (0 + sqrt12)/2). This simplifies to (2,sqrt3), which is your answer.

How do you find the hypotenuse of an equilateral triangle?
You can't as there is no hypotenuse in an equilateral triangle. The hypotenuse is the side of a triangle which is opposite a right angle (90°); all angles in an equilateral triangle are 60°.

What is the height of an equilateral triangle with the side lengths of 18 center meters?
In effect an equilateral triangle is made up of two right angle triangles joined together so use Pythagoras' theorem to find the height:- 182-92 = 243 and the square root of this will be the height of the equilateral triangle which is about 15.588 cm

How do you find the length of a triangle when perimeter is given?
If the triangle is equilateral, you simply divide the perimeter by three to find the length of each side. If the triangle is not equilateral, you will need more information to determine the length of each side.
