  1. 3. PLAIN ARCH
  2. 4. Definition: A PLAIN ARCH is that type of pattern in which ridges enter upon one side, make a rise or a wave in the center and flow or tend to flow out upon the opposite side. Classified as “AA” PLAIN ARCH

  8. 12. A TENTED ARCH is that type of pattern which possesses either an angle, an upthrust or two of the three basic characteristics of the loop. Classified as “TT” TENTED ARCH
