Final answer:
A direct proof in geometry involves a logical chain of steps using known facts and properties to prove a statement is true.
Step-by-step explanation:
A direct proof in geometry is described as a logical chain of steps, supported by postulates, definitions, and theorems, to prove a statement is true. It involves using known facts and properties to show the validity of the statement being proven. For example, if we want to prove that the opposite sides of a parallelogram are congruent, we would use the definition of a parallelogram and properties of congruent triangles to establish the equality of the opposite sides.
