What do the following terms mean: parallel lines, perpendicular lines, complementary angles, supplementary angles, vertically opposite angles?

Here are the definitions and diagram descriptions:

SECTION A

• 1.1 parallel lines: Lines that are in the same plane and never intersect, maintaining a constant distance from each other.

• 1.2 perpendicular lines: Lines that intersect to form a right angle ($90^\circ$).

• 1.3 complementary angles: Two angles whose sum is exactly $90^\circ$.

• 1.4 supplementary angles: Two angles whose sum is exactly $180^\circ$.

• 1.5 vertically opposite angles: When two straight lines intersect, the angles opposite each other are vertically opposite angles. These angles are equal in measure.

SECTION 2

• First diagram (lines L, M, H): This diagram shows two parallel lines (L and M) intersected by a transversal line (H).

• Second diagram (blurred parallel lines): This diagram shows two parallel lines.

• Third diagram (point A): This diagram shows a point labeled A.

• Fourth diagram (cross with right angles): This diagram shows two perpendicular lines intersecting.

• Fifth diagram (lines E-F, G-H with right angle): This diagram shows two perpendicular lines intersecting.
