set. - ? Angles paired with one another in a one-to-one correspondence between geometric figures. - ? Sides paired with one another in a one-to-one correspondence between figures. - ? If a one-to-one correspondence between the parts of two figures is such that the corresponding parts are equal, then the figures are congruent. - ? The angle formed by two sides of a triangle. - ?
