A right angle is exactly 90 degrees
None because a triangle can have only one 90 degree angle
It is a right angle triangle and the 3rd angle will measure 30 degrees
If one of the angles in a triangle is exactly 90 degrees, then it is a right-angle triangle.
If you mean an equilateral triangle then the 3rd angle is 60 degrees
right angle triangle
An angle whose measure is exactly 180 degrees is a straight angle.
A right angle is exactly 90 degrees
None because a triangle can have only one 90 degree angle
It is a right angle triangle and the 3rd angle will measure 30 degrees
A triangle has 180 degrees.A right triangle has exactly one angle measuring 90 degrees.If you know that one of the other angles of the triangle is 20 then your third angle is:180-90-20 = 70 degrees.
It is a right angle triangle
a TRIANGLE THAT HAS A 90 DEGREE ANGLE A right triangle is a triangle that has exactly 90 degrees for one angle.
If one of the angles in a triangle is exactly 90 degrees, then it is a right-angle triangle.
50 degrees if its a triangle
If you mean an equilateral triangle then the 3rd angle is 60 degrees
An obtuse triangle
