Yes.

Vertical angles can be acute, right (if the intersecting lines forming them are perpendicular) or obtuse.
Yes, all perpendicular angles form 90 degree angles.
ewan kÖ po. :) itanong bnaman sken. LOLS. ;D . Haha.

Vertical equal opposite angles are formed when lines intersect each other.
Vertical equal opposite angles are formed when lines intersect each other.
there are three acute angles in an acute triangle, because there are three corners.
The term parallelogram refers to a four sided geometrical figure (in other words, a quadrilateral) in which there are two sets of parallel sides. The angles can vary; they can be right angles, or they can be acute or obtuse angles, as long as there are two sets of parallel sides. Angles are not said to be vertical to each other. Angles can be perpendicular to each other, but not vertical or horizontal. If angles are perpendicular, then they are right angles, in other words, 90o angles. Lines can be vertical, but angles can't.
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
