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

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.
In an equilateral triangle all the angles are 60 degrees (i.e. acute angles)
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.
an equilateral triangle
scaleneAnother answer:It will be an equilateral triangle that has three equal interior angles of 60 degrees.
