The word demonstrate does not have a precise opposite, other than "fail to demonstrate" but sometimes we can make a distinction between demonstration and assertion. That is the difference between showing and telling.
The opposite would have to be "non-example" which is not an actual word although it appears in Wiktionary.The opposite of inspiration by example would be inspiration by appeal.
One can effectively demonstrate Newton's third law of motion by showing that for every action, there is an equal and opposite reaction. This can be done by using simple experiments such as pushing against a wall and feeling the force pushing back, or using a balloon to demonstrate how air escaping in one direction causes the balloon to move in the opposite direction.
The opposite of being late is being early. Being early means arriving at a destination or completing a task before the scheduled or expected time. This can demonstrate punctuality, preparedness, and respect for others' time.
Magnets that stick together demonstrate the principle of magnetic attraction by showing how opposite poles attract each other. When two magnets with opposite poles (north and south) come close together, they are pulled towards each other due to the magnetic force between them. This attraction is what causes the magnets to stick together.
To demonstrate the validity of a statement using proof by absurdity or contradiction, we assume the opposite of the statement is true and then show that this assumption leads to a logical contradiction or absurdity. This contradiction proves that the original statement must be true.
Empathetic individuals who demonstrate strong emotional intelligence and a capacity for caring, compassion, and understanding are at the opposite end of the spectrum from psychopaths. They are often in tune with the feelings and needs of others, prioritize relationships, and exhibit altruistic behavior.
Friction involves the interaction between objects when they are in contact. Newton's third law states that for every action, there is an equal and opposite reaction. In the context of friction, when one object applies a force on another, the second object exerts an equal but opposite force in the opposite direction, leading to the resistance or slowing down of motion.
The opposite of "prove" is "disprove." While to prove something means to establish its truth or validity through evidence or argument, to disprove means to demonstrate that something is false or invalid. Another related term could be "refute," which involves providing counterarguments or evidence that contradicts a claim.
The opposite of indolent is "diligent." While indolent describes a tendency to avoid activity or exertion, diligent refers to someone who is hardworking, committed, and actively engaged in their tasks. Diligent individuals demonstrate perseverance and a strong work ethic, contrasting sharply with the laziness associated with indolence.
The verb form of demonstration is demonstrate.Other verbs are demonstrates, demonstrating and demonstrated."We will demonstrate the steps to you"."They have demonstrated this before".
To prove that the opposite angles of a parallelogram are congruent, you need to establish that the figure is indeed a parallelogram, which can be done by showing that both pairs of opposite sides are parallel or that one pair of opposite sides is both equal and parallel. Once this is confirmed, you can use the properties of transversals and corresponding angles, or the fact that consecutive angles are supplementary, to demonstrate that the opposite angles are congruent. Therefore, a clear understanding of the properties of parallelograms and angle relationships is essential for the proof.
You did not specify if you're speaking of the verb or the noun. To show means to demonstrate something. The opposite of that would be to hide or to cover up. You could also say to confuse or to conceal.
