supplementary angles, are 2 angles whose sum is 180 degrees
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
angle B and angle D are supplements, angle B is congruent to angle D, angle A is congruent to angle A, or angle A is congruent to angle C
An angle of 98 degrees is an obtuse angle
A 12 degree angle is an acute angle.
reflex angle
It is: 180-115 = 65 degrees

2 angles whose sum is 180 are called supplementery angles.an example of supplementary angles are two right angles.=)
Right angle, obtuse angle, acute angle, supplementary angle, complementary angle, interior angle, exterior angle, adjacent angle
The angle of incidence
the angle of incidence is the initial ray angle and the angle of reflection is the reflected ray angle
A right angle is a angle with 90o
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
obtuse angle
It is a reflex angle
reflex angle!
First: A right angle is an angle of 90 degrees Second: An obtuse angle is an angle of 91 degrees to 179 degrees A right angle can not have an obtuse angle
