There are four types of triangles.
For an "equilateral triangle", all sides and angles have to be the same.
For an "isosceles triangle", 2 of 3 sides and angles have to be the same.
For a "scalene triangle", the "the same" rules don't apply.
For a "right-angled triangle", one corner has to be a right angle (90 degrees.)
For example in an equilateral triangle, as long as the sides are the same, they can add up to anything.
However, angles are different. In any given triangle, the angles must add up to 180 degrees.

How much rotational symmetry does triangle have?
It depends on the type of triangle. A scalene triangle (no equal sides) has no rotational symmetry. An isosceles triangle (2 equal sides) has rotational symmetry order 2. An equilateral triangle (3 equal sides) has rotational symmetry order 3. The order of rotational symmetry is how many time a shape will fit over itself during one complete rotation.
How much degrees does a square equal?
A Square Or A Quadrilateral Or A Polygon With Four Straight Sides Has 360 Degrees!!=] I Know This Is Not The Question But It Is Related] A Triangle Has 180 Degrees!!=)
How much does an isosceles triangle equal all together?
180* or 120*, not sure
How much degrees are in a isoscelese triangle?
The angles inside any triangle sum to 180 degrees. Isosceles simply means two sides are the same length.
How many parallel sides do a triangle have?
none. A triangle, in standard 2 dimensions cannot have any parallel sides. Let's show without going into formal proof. Let's say that you try to make a triangle with 2 parallel sides. -------------side a------------- |C | | |side b | | |A -------------side c--------------- Side a & b intersect at vertex C. Side b & c intersect at vertex A, and since sides a & c are parallel, they will never intersect, so there is no third vertex, so it's not a polygon, much less a triangle.
