The triangle contains a 90 degree angle, making it a right-angled triangle.
Yes because an equilateral triangle contains 3 equal 60 degree angles whereas a right angle triangle contains a 90 degree angle and two acute angles that add up to 90 degrees.
A right triangle has one angle that is a right angle (90 degrees). An obtuse triangle has one angle that is obtuse (between 90 and 180 degrees). An acute triangle is a triangle in which all three angles are acute (less than 90 degrees).
A triangle with a 90° angle is called a "right triangle."
