It depends on the other two angles.. If all the angles in the triangle are 60 degrees(i.e equal) its an equilateral triangle :D
A right angled scalene triangle
A right angles triangle, as one of the angles in the triangle is 90 degrees.
It is a right angle triangle providing that the 3rd angle is 30 degrees.
It is a right angle triangle and the 3rd angle will measure 30 degrees
The last angle would have to be 60 degrees as well. Since there are 180 degrees in a triangle, 60+60=120 and 180-120=60, it has to be 60 degrees.
A right angled scalene triangle
The 3 interior angles of an equilateral triangle each measures 60 degrees
A right angles triangle, as one of the angles in the triangle is 90 degrees.
Obtuse triangle
an equalateral triangle 60 degrees 60 degrees 60 degrees
It is a right angle triangle providing that the 3rd angle is 30 degrees.
It is a right angle triangle and the 3rd angle will measure 30 degrees
The last angle would have to be 60 degrees as well. Since there are 180 degrees in a triangle, 60+60=120 and 180-120=60, it has to be 60 degrees.
an equilateral triangle
No. By definition, the angles of an equilateral triangle are 60 degrees, 60 degrees, and 60 degrees. A right triangle, on the other hand, must have a 90 degree angle.
In an equilateral triangle all the angles are 60 degrees (i.e. acute angles)
A right-angle triangle
