A right angle has 90 degrees.
A right angle is 90 degrees.
The sum of all angles in any triangle is 180o The largest angle in aright angle triangle is 90o
A right triangle is a triangle with one right angle.
in a right angled triangle there is only 1 right angle
the 90 degree angle between two perpendicular lines; if your wondering what perpendicular lines are they are lines that cross each other at an intersection.
converse
A right angle is an angle of 90 degrees.
An angle of 175 degrees is an obtuse angle
When an angle has a measure of 120 degrees, it is an obtuse angle. When an angle is an obtuse angle its measure is between 90 and 180 degrees. That is: 90 degrees < obtuse angle < 180 degrees.
No such thing as opposite of acute angle. An ACUTE angle is an angle of less than 90 degrees. A RIGHT angle is an angle of 90 degrees only. An OBTUSE angle is an angle between 90 degrees and 180 dehrees. An angle of 180 degrees is a straight line. A REFLEX angle is an angle between 180 degrees and 360 degrees.
The supplement of an angle is the angle that, when added to the original angle, equals 180 degrees. The complement of an angle is the angle that, when added to the original angle, equals 90 degrees. Therefore, the supplement of the complement of a 38-degree angle would be the angle that, when added to the complement of 38 degrees (52 degrees), equals 180 degrees. This angle would be 128 degrees.
