Question

question 8 (multiple choice worth 4 points) (01.06r mc) kyle is creating a frame for a model car. he begins by piecing two rods together, as shown in the diagram. justify why ∠aec is a right angle. definition of parallel lines. definition of perpendicular bisector. definition of complementary angles. definition of adjacent angles.

Explanation:

The two rods are perpendicular to each other as indicated by the right - angle symbol at the intersection. By the definition of perpendicular lines, when two lines are perpendicular, the angles formed at their intersection are right angles. ∠AEC is an angle formed by two perpendicular lines (rods), so it is a right angle based on the definition of perpendicular lines.

Answer:

Definition of perpendicular lines
