To graph a parabola you must find the axis of symmetry, determine the focal distance and write the focal as a point, and find the directrix. These are all the main points you need to be able to draw a parabola.
If the triangle is equilateral, you don't have a problem, but if not you have to measure the sides.
no because an equilateral triangle is a total of 180 degrees not 120. but if you need to find the missing angle or missing degree then yes!
Find out what 1 side is and multiply by 3 to find perimeter

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°.
It is called and equilateral triangle. You can find more information about equilateral polygons here: http://www.answers.com/equilateral
Find the area of an equilateral triangle if its perimeter is 18 ft
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.

If a triangle is isosceles, then it is equilateral. To find the converse of a conditional, you switch the antecedent ("If ____ ...") and consequent ("... then ____."). (Of course, if not ALL isosceles triangles were equilateral, then the converse would be false.)
If the triangle is equilateral, you don't have a problem, but if not you have to measure the sides.
An equilateral triangle has 3 equal interior angles each of 60 degrees. There are two right angled triangles in an equilateral triangle. So we can use trigonometry to find the length of one side of the equilateral triangle then multiply this by 3 to find its perimeter. Hypotenuse (which is one side of the equilateral) = 15/sin 60 degrees = 17.32050808 17.32050808 x 3 = 51.96152423 Perimeter = 51.96152423 units.
Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
