Poach eggs in a wide, shallow pan filled with simmering water. Using the handle of a slotted spoon, swirl the simmering water to create a whirlpool or vortex (this will help the eggs to hold their shape). Crack the eggs, one or two at a time, directly into the centre of the whirlpool.
Confidence votes 35. The Definition of Congruent Figures (which is a proof) says that if two figures have corresponding sides congruent and corresponding angles congruent, then the figures are to be congruent. Minor edit?
Congruent angles: Two angles that have the same measure. The arc marks on the angles below denote congruence. Adjacent angles: Two coplanar angles with a common side, a common vertex, and no common interior points. The example below shows angles ADB and BDC are complementary angles.
