An equilateral triangle has 3 interior 60 degree angles but a right angle triangle can have 3 interior angles of 90, 60 and 30 degrees
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
A right triangle because all triangles equal 180 degrees. 180-60=120 120-30=90
No. One isn't enough. It must have two of them.
It is an equilateral triangle because its 3rd angle has to be 60 degrees
An equilateral triangle has two 60 degree angles which must make its third angle also 60 degrees

A 30-60-90 right triangle is one in which the three angles of the triangle 30, 60 and 90 degrees. The length of the sides of such a triangle have the ratio 1:2:square root of 3. The 1 is opposite the 30 degree angle, the 2 is opposite the 60 degree angle and the square root of 3 is opposite the 90 degree angle.

Acute. A 60-degree angle is also called a 'special triangle angle' since it appears in the special triangle 1, root(3), 2
100
There are 60 minutes of angle in one degree of angle.
An equilateral triangle has three acute (60 degree) angles.
