Question

transversal vocabulary
if two are parallel, then alternate interior angles are ______
options: complementary, equal, supplementary, congruent

Explanation:

The question is about transversal vocabulary in a geometric context (since it mentions "lines are parallel, then alternate interior angles..."). In geometry, when two parallel lines are cut by a transversal, alternate interior angles are congruent. Let's analyze the options:

• "complementary" means angles add up to 90°, not related to alternate interior angles of parallel lines.
• "supplementary" means angles add up to 180°, also not the case here.
• "disconnected" is not a term related to angle relationships in this context.
• "congruent" means having the same measure, which is the property of alternate interior angles when lines are parallel.

Answer:

The correct option is the one labeled with "congruent" (the last option, assuming the options are ordered as complementary, supplementary, disconnected, congruent). So, if we assume the options are:
A. complementary
B. supplementary
C. disconnected
D. congruent

Then the answer is D. congruent
