Congruent line segments are usually indicated by drawing the same amount of little tic lines in the middle of the segments, perpendicular to the segments. AAS (Angle-Angle-Side): If two pairs of angles of two triangles are equal in measurement, and a pair of corresponding non-included sides are equal in length, then the triangles are congruent. Knowledge of the relationships between angles can help in determining the value of a given angle. There may be Turns, Flips or Slides, Too! Uses of congruent angles.
