A triangle has no right angles when it is not a right angle triangle as for example as in the case of an equilateral triangle that has 3 equal 60 degree angles.
a 'SCALENE' triangle. ; No equal sides, and no equal angles. An ISOSCELES triangle has two equal sides and two equal angles. An EQUILATERAL tringle has three equal sides and three equal angles all at 60 degrees. A RIGHT ANGLED triangle has one right angle (90 degrees) in it.
No, an equilateral triangle has all sides of equal length. All angles are 60 degrees. A right triangle has a 90 degree angle and allsides can never be equal
No, because the angles of a triangle have to total 180 degrees and if there are three angles in a triangle, 90 * 3 cannot equal 180. To have three equal sides, the angles must equal 60 degrees 60 * 3 = 180.
No. A regular polygon has all sides equal and all angles equal. Neither of those properties can be true of a right triangle. A regular triangle is an 'equilateral one'. Its sides are equal, and each of its angles is 60 degrees.

Is 682 equal to 602 + 322 ? If so it's a right-angled triangle...
No, an equilateral triangle has all sides of equal length. All angles are 60 degrees. A right triangle has a 90 degree angle and allsides can never be equal

Equilateral. The angles will all equal 60 degrees.

No. They are usually different.An isosceles triangle has two equal angles and two equal adjacent sides. An isosceles triangle with three 60° angles is the equilateral triangle.Only one isosceles triangle, which has two 45° angles, includes a right angle and is called an isosceles right triangle.

No, an equilateral triangle can't have a right angle, because an equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees.
No. The equilateral triangle has all three sides equal to 60 degrees. The right triangle has a 90 degree angle making it different from an equilateral.
Never. All equilateral triangles have equal angles, which means every angle must be 60 degrees and therefore not right.
