Answer:
1. Two lines (on the same plane) are parallel to each other if they never intersect each other, ragardless of how far they are extended on either side.
2. There would be 12 angles formed by three parallel lines and one traversal.
These angles might be of no more than 2
different measures.
3.
a) The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°. Such angles are also known as supplementary angles. One angle is called the supplement of the other.
b) 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.
c) Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.
4. Transversal is a line that intersects two or more other (often parallel ) lines.
