Any angle that would be less than 80 degrees would be known to be called an "Acute Angle". Therefore, your correct answer would then be known to be called an Acute Angle.

Answer:
If AB and CD intersect at point P such that P is between A and B and is also between C and D, then ∠APC and ∠BPD are a pair of vertical angles.
Step-by-step explanation:
The diagram is a sketch of a counterexample. Notice that ∠APC and ∠BPD are actually the same angles and are not vertical angles.
If P is between A and B and is also between C and D, then ∠APC and ∠BPD are vertical angles. Then the statement can be completed as:
If AB and CD intersect at point P such that P is between A and B and is also between C and D, then ∠APC and ∠BPD are a pair of vertical angles.
3x + 2y - 2x + y + 12 —> x + 3y + 12
4y + 3y + 3x - 6y - 10 -2 —> 3x + y - 12
12 - 3y - 2x + x + 2x —> x - 3y + 12
x + 3y + 2x - 3x + 7 + 5 —> 3y + 12
