The three sides are the same length but that length can be anything you like. The angles are 60 degrees each.
equilateral traingle
If it is an equilateral, for example if one side was 3 then you times the 3 by 3 because there are 3 equal sides. However, if it's not an equilateral you have to add them all up.
An isoceles triangle has at least two sides equal; an equilateral has three sides equal so it is also isoceles; and since all angles are acute it is also an acute traingle
Only when its an equilateral triangle then it is a regular polygon
It is called an equilateral triangle.
There are three equal sides in an equilateral triangle.

Equilateral Triangle - if that is what you mean
This traingle is an equilateral traingle: which consists of all the three sides and angles to be congruent. The angles inside the triangle, just like any normal traingle, add up to be 180 degrees. The opposite of this traingle is the Scalene triangle which has all the three sides to be Uncongruent and has different angles. All the angles of ALL traingles still add up to 180 Degrees. The Isoceles triangle consists of two equal sides and one extravagantly large one side. Therefore, because of the previous properties, an isosceles traingle has two congruent angles and usually one obtuse or acute angle. The last triangle, the right triangle, has one right angle. It is the only triangle that is capable with triginomical ratios and the Pythagorean Theorem.
traingle
The interior angles of any triangle (not traingle) always sum to 180 degrees. Whether or not it is equilateral (not eguilateral) is irrelevant.
3... If its a traingle it has 3 angles where the sides meet.
