Question

all perpendicular angles measure 90°. any point on one parallel line is the same distance from the other line on a perpendicular transversal. they are measures of the same segment. congruence (4, 6, 5) corresponding parts of congruent figures are congruent (7).

Explanation:

The statements are basic geometric properties. Perpendicular angles are always 90 degrees. Parallel lines have a constant perpendicular - distance between them. Congruence means equal in measure, and corresponding parts of congruent figures are congruent.

Answer:

These are fundamental geometric concepts.
