Question

directions: select the best response. what is the contra - positive of the following conditional statement? “if they are opposite angles formed by two intersecting lines, then they are vertical angles.” o if they are vertical angles, then they are opposite angles formed by two intersecting lines. o if they are not opposite angles formed by two intersecting lines, then they are not vertical angles. o if they are not vertical angles, then they are not opposite angles formed by two intersecting lines. o if they are not vertical angles, then they are not opposite angles formed by two intersecting lines.

Explanation:

Vertical angles are formed by two intersecting lines and are opposite angles. The contra - positive of a conditional statement "if p then q" is "if not q then not p". Here, the original statement is "if they are opposite angles formed by two intersecting lines, then they are vertical angles". Its contra - positive is "if they are not vertical angles, then they are not opposite angles formed by two intersecting lines".

Answer:

If they are not vertical angles, then they are not opposite angles formed by two intersecting lines.
