A. This study is an experiment, since it was based on a random sample.
Step-by-step explanation:
Simple random sampling is a probabilistic sampling procedure that gives each element of the target population and each possible sample of a given size the same probability of being selected.
The corresponding angles of triangle ABC and its image are congruent
<h3>How to determine the relationship?</h3>
The transformation rule is given as:
A rotation of 180 degrees about the origin
The rotation transformation is a rigid transformation.
This means that it does not alter the side lengths and the angle measure of the shape being rotated
Hence. the corresponding angles of triangle ABC and its image are congruent

Answer:
D. 4x = 20
Step-by-step explanation:
Four times a number is 20
Let x be the number
4x = 20
This statement is false as all vertical angles are considered congruent but not all congruent angles are considered vertical angles. Any obtuse or acute angle may be considered congruent. If the angle from point A to B is 110 and the angle between B to C is 110 as well then they are congruent
