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.
A right triangle. All the angles of a triangle add up to 180. 30+60+x=180. subtract 30 from both sides, then 60 from both sides and x=90
It is Pythagoras' theorem that states for any right angle triangle its hypotenuse when square is equal to the sum of its squared sides.
None ! An equilateral triangle has three angles of 60 degrees.

Is 682 equal to 602 + 322 ? If so it's a right-angled triangle...

Pythagoras' theorem:- a2+b2 = c2 where a and b are the sides of a right angle triangle and c is its hypotenuse
an equilateral triangle (all sides are adjacent and 60 degrees)
It is Pythagoras' theorem that states for any right angle triangle its hypotenuse when square is equal to the sum of its squared sides.
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.
None ! An equilateral triangle has three angles of 60 degrees.
Equilateral Triangle. The sides are equal in length as well.
Yes, actually it has to be. The only type of triangle with even sides is an equilateral triangle, but all of the angles of an equilateral are 60 degrees, because everything is equal and 180(total degrees within a triangle)/3(number of angles)=60(degrees per angle of an equilateral).
