Summary
Q. Can 3 angles be complementary?
Three angles or more angles whose sum is equal to 90 degrees cannot also be called complementary angles. Complementary angles always have positive measures. It is composed of two acute angles measuring less than 90 degrees.

Q. How do you know if an angle is supplementary?
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.
| Angle Type | Angle measure |
|---|---|
| Acute angle | Greater than 0 °, Less than 90° |
| Right angle | 90° |
| Obtuse angle | Greater than 90°, less than 180° |
| Straight angle | 180° |
Q. What are the angle relationships in parallel lines?
When the lines are parallel, the corresponding angles are congruent . When two lines are cut by a transversal, the pairs of angles on one side of the transversal and inside the two lines are called the consecutive interior angles .
Q. What are the angle pair relationships?
In Geometry, there are five fundamental angle pair relationships: Complementary Angles. Supplementary Angles. Adjacent Angles.
Q. What are the three angle relationships?
Angle Relationships (Types of Angles)
- Congruent Angles.
- Adjacent Angles.
- Vertical Angles.
- Corresponding Angles.
- Exterior Angles.
- Interior Angles.
Q. What is the relationship between triangle sides and angles?
Relationship between sides and angles. In any triangle, the largest side and largest angle are opposite one another. In any triangle, the smallest side and smallest angle are opposite one another. In any triangle, the mid-sized side and mid-sized angle are opposite one another.
Q. What is the relationship between angle 4 and angle 5?
Angle 4 and angle 5 are interior angles on the same side of transversal , which means the sum of angle 4 and angle 5 will be equal to 180° .
Q. What is the relationship between Angle 8 and 4?
Corresponding angle : The angles in matching corners are called Corresponding Angles. Corresponding angle are equal. Therefore, ∠8 , ∠4 are Corresponding angle.
Q. Do alternate angles equal the same?
Corresponding angles The two angles marked in each diagram below are called alternate angles or Z angles. They are equal.
Q. What is the relationship for angle 9 and angle 16?
Angle 9 and angle 16 are vertical. If angle 9 is 82 degrees, what is the measure of angle 16? Two transversals cut a pair of parallel lines. Kate said that since angle 1 and angle 6 are vertical, they should add up to 180 degrees.
Q. What kind of angle is 160?
An obtuse angle is a type of angle whose degree measurement is more than 90° but less than 180°. Examples of obtuse angles are: 100°, 120°, 140°, 160°, 170°, etc. ∠ PQR is an obtuse angle because it’s less than 180° and greater than 90°.
Q. Why is it called a right angle and not a left angle?
Right, meaning “correct”, and right, meaning “straight”, do have the same root, but “right angle” derives from the second rather than the first. A right angle was described in ancient geometry as the meeting of two right, ie straight, lines, with regard to dimensional axes.
