Using congruent triangles, one can prove that the rhombus is symmetric across each of these diagonals. It follows that any rhombus has the following properties:
 Question: does a rhombus have two sets of parallel lines Context: In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. This dilutes the O in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce peak in-cylinder temperatures. NO is produced in a narrow band of high cylinder temperatures and pressures. Another primary benefit of external EGR valves on a spark ignition engine is an increase in efficiency, as charge dilution allows a larger throttle position and reduces associated pumping losses.

While in some jobs, this is a minor transgression or not even worthy of sanctioning, in other workplaces, this is considered gross misconduct and may be grounds for disciplinary action, including possible termination of employment. Recently however, there has been a movement in support of sleeping, or napping at work, with scientific studies highlighting health and productivity benefits, and over 6% of employers in some countries providing facilities to do so. In some types of work, such as firefighting or live-in caregiving, sleeping at least part of the shift may be an expected part of paid work time. While some employees who sleep while on duty in violation do so intentionally and hope not to get caught, others intend in good faith to stay awake, and accidentally doze.
 Question: can i be sacked for falling asleep at work Context: Dust are fine particles of matter. It generally consists of particles in the atmosphere that come from various sources such as soil, dust lifted by weather (an aeolian process), volcanic eruptions, and pollution. Dust in homes, offices, and other human environments contains small amounts of plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, human skin cells, burnt meteorite particles, and many other materials which may be found in the local environment.
