This is called a right angle.
right angle
90degrees
No, it equals 90degrees.
complement 90degrees-49 = 41degrees supplement 90degrees-49 = 131degrees
Right angle is 90degrees acute angle is less than 90 degrees
if you add them they will equal 90degrees.
an obtuse angle is more than 90degrees and less than 180 degrees. this is call a reflex angle...
Obtuse.
Your question contains the answer. It is a 'right' triangle.
A right triangle has one angle that is always 90degrees. The other angles vary from less than 90degrees to greater than 0degrees. The equilateral triangle always has all of its angles equal to 60degrees.
are you talking about obtuse (91-179), a straight angle (180), or reflex (181-359)
