It is called a 30-60-90 triangle and it is a right triangle whose sides are always in the ratio:
1:2:Square root (3).
A right angles triangle, as one of the angles in the triangle is 90 degrees.
It's called an equilateral triangle. All 3 sides are equal length and all 3 angles are equal (60 degrees)
When all angles in a geometric figure are equal, the figure is described as "equiangular." In the context of polygons, an equiangular polygon has all its interior angles equal, such as an equilateral triangle or a square. For example, in an equilateral triangle, each angle measures 60 degrees, while in a square, each angle measures 90 degrees.
A triangle with all three angles measuring 60 degrees is called an equilateral triangle.
A triangle that measures less than 90 degrees is called an acute triangle. In an acute triangle, all three interior angles are less than 90 degrees. This property distinguishes it from right triangles, which contain one angle equal to 90 degrees, and obtuse triangles, which have one angle greater than 90 degrees.

They are called obtuse angles.
A triangle with all three angles measuring 60 degrees is called an equilateral triangle.
Equilateral, meaning all sides of equal length. The triangle is also equiangular, having all three angles of equal measure. Since the interior angles of a triangle sum to 180 degrees, each angle measures 60 degrees.
A triangle that measures less than 90 degrees is called an acute triangle. In an acute triangle, all three interior angles are less than 90 degrees. This property distinguishes it from right triangles, which contain one angle equal to 90 degrees, and obtuse triangles, which have one angle greater than 90 degrees.
They are called complementry angles
A triangle with one right angle and two acute angles is called a right triangle. In a right triangle, one of the angles measures 90 degrees, making it a right angle, while the other two angles are acute, meaning they measure less than 90 degrees each. The Pythagorean theorem can be applied to solve for the lengths of the sides of a right triangle.
They are then complementary angles
If all of the 3 acute angles are 60 degrees then it is an equilateral triangle if not then it could be a scalene triangle.
A scalene triangle
A triangle with all angles congruent are called equilateral. Each angle is 60 degrees.
