Answer:
1----Right angle- 90°
2---Acute - less than90°
3---Obtuse angle- more than 90°
4---- Complementary angle- 90°
5----Supplementary angles -180°
Answer:
correct answer friend
1)Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.
2)In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.
3)An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees. However, A reflex angle measures more than 180 degrees but less than 360 degrees.
4)Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
5)Two angles are called supplementary when their measures add up to 180 degrees.
6)Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap. they have a common side (line CB) ... they have a common vertex (point B)
7)A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
8)The angles opposite each other when two lines cross. They are always equal. In this example a° and b° are vertically opposite angles.
9)In geometry, a transversal is a line that passes through two lines in the same plane at two distinct points. Transversals play a role in establishing whether two other lines in the Euclidean plane are parallel.
