Final answer:
To know why the chosen answer is correct, understanding the distinctions between different types of angles is important.
Step-by-step explanation:
To determine why the answer you chose from the previous question is correct, we need to understand the distinctions between different types of angles. The options given are adjacent angle, right angle, vertical angle, and supplementary angle.
An adjacent angle shares a common side and vertex with another angle. A right angle measures 90°, a vertical angle is formed by two intersecting lines, and supplementary angles add up to 180°.
By understanding these definitions, you can determine which type of angle matches the characteristics described in the previous question and choose the correct answer.
