Answer:
related angles- Related angles are the pairs of angles and specific names are given to the pairs of angles which we come across. These are called related angles as they are related with some condition. Complementary angles: When the sum of the measures of two angles is 90°, such angles are called complementary angles.
complementary angles- angles less that 90 degree
Answer:
1.Related angles are the pairs of angles and specific names are given to the pairs of angles which we come across. These are called related angles as they are related with some condition. 2.Complementary angles: When the sum of the measures of two angles is 90°, such angles are called complementary angles either of two angles whose sum is 90°.
3.Supplementary angle -either of two angles whose sum is 180°.
4.Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap.
5.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.
6. Vertically Opposite Angles are the angles opposite each other when two lines cross. "Vertical" in this case means they share the same Vertex (corner point), not the usual meaning of up-down.
7. pair of lines, line segments or rays are intersecting if they have a common point. This common point is their point of intersection.
8. the intersection of a line and a line can be the empty set, a point, or a line.
9. of a line) cutting a system of lines
10. In geometry, a transversal is a line that passes through two lines in the same plane at two distinct points. ... The intersections of a transversal with two lines create various types of pairs of angles: consecutive interior angles, corresponding angles, and alternate angles.
11.In geometry, a transversal is a line that intersects two or more other (often parallel ) lines. If two parallel lines are cut by a transversal, then the alternate interior angles formed are congruent .
