In mathematics, vertical angles are always congruent. Vertical angles are the angles positioned opposite from each other when two lines intersect. They are called vertical because ...
one of two opposite and equal angles formed by the intersection of two lines.
Vertical Angles are the angles opposite each other when two lines cross. "
Vertical" in this case ... The interesting thing here is that vertical angles are equal:
Vertical Angles are the angles opposite each other when two lines cross. They
are always equal. In this example a° and b° are vertical angles. Try moving the ...
One thing to consider in this equation is that in cases where the meniscus is convex (i.e. the contact angle
is greater than 90 degrees), the cosine component of this equation will be negative which means that the liquid-solid surface tension will be positive.
