If you mean an equilateral triangle then the 3rd angle is 60 degrees
It is a right angle triangle and the 3rd angle will measure 30 degrees
There are only 4 possible numbers which could be measures of the angles for the quadrilateral. Each of the infinitely many other measures, such as 36.57 degrees, could NOT be the measure.
25 degrees
The third angle is 34.5 degrees
77 degrees
It is a right angle triangle and the 3rd angle will measure 30 degrees
They each measure 60 degrees
20 degrees

25 degrees
105
Each of the 3 angles measures 60 degrees. There are 180 degrees in a triangle.
77 degrees
Triangles measure 180 degrees. A triangle that has one 90 degree angle is known as a right triangle.
The third angle is 34.5 degrees
The missing angle measure is 100 degrees.
