Supplementary angles are two angles whose measures add up to 180 degrees, while complementary angles are two angles whose measures add up to 90 degrees. For example, if one angle measures 70 degrees, its supplementary angle would measure 110 degrees, and its complementary angle would measure 20 degrees. Both concepts are fundamental in geometry, particularly in the study of angle relationships.
If A and B are the angles, then A + B = 180 and A - B = 20 So that 2A = 200 ie A = 100 and then B = 80 So the two angles are 100 and 80 degrees.
Pairs of Angles 1.Complementary Angles -are two angles together complete a right angle. *The two angles need not be to be adjacent. -to find the complement angle subtract the given angle from 90°. Ex: Give the complement of 65°. 1. 90°-65° =25° (25+ 65=90) 2. 90°-70° =20° (20+ 70=90) 2.Supplementary Angles -are two angles whose measurements are equal to 180°. *The angles not also be adjacent. -To find the supplement angle, subtract the given angle from 180°. Ex: 1. Give the supplement of 130°. 180°-130°=50° 3.Adjacent Angles -two angles with a common side and the same vertex. 4.Vertical angles -are opposite angles formed two intersecting lines. They have a common vertex but no common side.
The complement of an angle is found by subtracting the angle from 90 degrees. For 110 degrees, the complement would be 90 - 110, which equals -20 degrees. Since angles cannot be negative in this context, 110 degrees does not have a complement in the standard definition of complementary angles.
160 The 2 angles must equal 180 degrees, so 160 is the answer.

20 degrees
Its supplementary angle is 160 degrees because supplementary angles add up to 180 degrees
If A and B are the angles, then A + B = 180 and A - B = 20 So that 2A = 200 ie A = 100 and then B = 80 So the two angles are 100 and 80 degrees.

20 degrees
20 degrees. the definition of a supplementary angle is two angles that add up to 180 degrees.
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 20 degree angle is equal to 180 - 20 = 160 degrees.
The complement of an angle is found by subtracting the angle from 90 degrees. For 110 degrees, the complement would be 90 - 110, which equals -20 degrees. Since angles cannot be negative in this context, 110 degrees does not have a complement in the standard definition of complementary angles.
160 The 2 angles must equal 180 degrees, so 160 is the answer.
Correct. Congruency means that two triangles have three pairs of congruent angles and corresponding sides of the same lengths. A pair of triangles with three pairs of congruent angles but sides of different lengths are similar, not congruent.
20....or maybe 18
