The base angles theorem states that if the sides of a triangle are congruent (Isosceles triangle)then the angles opposite these sides are congruent.
When the contact angle is stable (static) over time there is no penetration of liquid into the substrate and the volume and base diameter are both constant. If the contact angle is decreasing over time, the reason can be penetration (loss of volume) or spreading.
