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.
Types of Triangle by Angle. In an equiangular triangle, all the angles are equalâeach one measures 60 degrees. An equiangular triangle is a kind of acute triangle, and is always equilateral. In a right triangle, one of the angles is a right angleâan angle of 90 degrees. A right triangle may be isosceles or scalene.In an obtuse triangle, one angle is greater than a right angleâit is more than 90 degrees.An obtuse triangle may be isosceles or scalene. In an acute triangle, all angles are less than right anglesâeach one is less than 90 degrees. An acute triangle may be equilateral, isosceles, or scalene.ypes of Triangle by Angle.
