To analyze the statement "If two angles are both 25 degrees, then they are congruent angles," we first identify its components:

  1. Original Statement (P → Q):
    • P: "Two angles are both 25 degrees."
    • Q: "They are congruent angles."

Now we can define the three derived forms:

  1. Converse: The converse of an implication is formed by reversing the two parts, thus it becomes:

    • Q → P: "If they are congruent angles, then they are both 25 degrees."
    • Answer: "if two angles are congruent, then they are both 25 degrees".
  2. Inverse: The inverse negates both parts of the original statement, which gives us:

    • ¬P → ¬Q: "If two angles are not both 25 degrees, then they are not congruent angles."
    • Answer: "If two angles are not 25 degrees, then they are not congruent angles."
  3. Contrapositive: The contrapositive negates and reverses the original statement:

    • ¬Q → ¬P: "If they are not congruent angles, then they cannot both be 25 degrees."
    • Answer: "if two angles are not congruent angles, then they cannot both be 25 degrees."

Now, let's summarize:

  1. Converse of the statement:

    • Answer: if two angles are congruent, then they are both 25 degrees.
  2. Inverse of the statement:

    • Answer: If two angles are not 25 degrees, then they are not congruent angles.
  3. Contrapositive of the statement:

    • Answer: if two angles are not congruent angles, then they cannot both be 25 degrees.
