An old brick has a natural cavity on one side, providing a cool daytime slug hiding place. Look under any you have around the garden and dispose of the slugs found sheltering. Purposely position a few to create slug shelters, and check daily. A brick also makes a handy squishing implement.
Q Angle of the Knee. The Q angle of the knee is a measurement of the angle between the quadriceps muscles and the patella tendon and provides useful information about the alignment of the knee joint.
As can be seen from the figure above, when two lines intersect, four angles are formed. Each opposite pair are called vertical angles and are always congruent. The red angles â JQM and â LQK are equal, as are the blue angles â JQL and â MQK. Vertical angles are also called opposite angles.
