The soil texture triangle is one of the tools that soil scientists use to visualize and understand the meaning of soil texture names. The textural triangle is a diagram which shows how each of these 12 textures is classified based on the percent of sand, silt, and clay in each. Note: these percentages are based on the USDA definition of sand and silt only. Follow these steps to determine the textural class name of your soil sample: 1) Determine the percent sand of your sample and find that number on the bottom of the triangle. Note that the numbers read from right to left, not left to right.
Noun[edit] ( 1 geometry) A triangle having at least two sides equal.  Usage notes[edit] In original usage, an isosceles triangle was understood to have the third side unequal to the other two, that is, an isosceles triangle has exactly two equal sides. An equilateral triangle is, however, a special case of an isosceles triangle, having all three sided equal. Of trilateral figures, an equilateral triangle is that which has its three sides equal, an isosceles triangle that which has two of its sides alone equal, and a scalene triangle that which has its three sides unequal.
