Question

lines that run in the same direction, never intersecting, are called lines.
a is a line that crosses at least two other lines.
angles that are in the same position on two parallel lines in relation to a transversal are called angles.
angles are pairs of angles on opposite sides of the transversal but inside the parallel lines.
two angles that sum up to 90° are called angles

Explanation:

1. Parallel lines are defined as lines that run in the same direction and never intersect.
2. A transversal is a line that crosses at least two other lines.
3. Corresponding angles are in the same position on two parallel lines relative to a transversal.
4. Alternate interior angles are pairs of angles on opposite sides of the transversal but inside the parallel lines.
5. Complementary angles are two angles that sum up to \(90^{\circ}\).

Answer:

1. parallel
2. transversal
3. corresponding
4. alternate interior
5. complementary
