No all triangles have right angle a right angle is a angle measurement of 90 degrees. some triangles are equal sides yes like 60 degrees on each angle. and the angle must equal 180 degrees. not 360 that is a whole different shape.
Not all triangles have right angles. A triangle is simply a closed figure with three sides and three angles, the sum of the degrees of which add up to 180°.
For instance, an equilateral triangle will will have all three angles equal to each other (60°, 60°, 60<span>°).
Some triangles may have right angles (90</span><span>°), but not all do. Hope that helped =)</span>
