I think you are mixing up concepts. The short anwer is "No", but the real answer seems more complicated to me since "acute" typically refers to angles, where two lines meet, and acute angles are less than 90 degrees. However, since two "vertical" lines are headed "straight up" and, therefore, in the same direction, they will never meet to create an angle at all (as your question implies); they are parallel. Most mathmeticians would not ask the question, "are parallel lines acute?" You might as well ask, "When you start dating Angelina Jolie, what will she like best about you?" The second part of the question is moot since the first part will never happen.
What else can I help you with?
A pair of vertical angles are acute true or false?
Sometimes
Do a pair of intersecting lines form two pairs of vertical angles?
Yes, a pair of intersecting lines always forms a pair of vertical angles.
What is a rhythmic unit enclosed between a pair of vertical lines?
A rhythmic unit enclosed between a pair of vertical lines is a measure, or bar.
Can a vertical angle an obtuse angle?
Vertical angles can be acute, right (if the intersecting lines forming them are perpendicular) or obtuse.
What lines are lines that form acute or obtuse angles at the point of intersection?
Vertical equal opposite angles are formed when lines intersect each other.
What are lines are lines that form acute or obtuse angles at the point of intersection?
Vertical equal opposite angles are formed when lines intersect each other.
What is a pair of congruent angles that are formed when two lines intersect?
Vertical angel
What is a pair of opposite angles formed by intersecting lines called?
vertical angles
Did vertical angles are two nonadjacent angles formed by a pair of intersecting lines?
yes
What shape has only one pair of perpendicular lines?
I think it is either a right triangle, square, pentagon, or rectangle.
What are all of the situations in which the statement Two vertical angles are supplementary is true?
If the lines are perpindicular then each pair of vertical angles are supplementary
What is a polygon that has 1 pair of parallel lines 2 acute angles and 2 obtuse angles?
trapezoid
