Plane Geometry is about flat shapes like lines, circles and triangles ... shapes that can be drawn on a piece of paper Hint: Try drawing some of the shapes and angles as you learn ... it helps. Point, Line, Plane and Solid Line elements are connected only at common nodes, forming framed or articulated structures such as trusses, frames, and grids. Line elements have geometric properties such as cross-sectional area and moment of inertia associated with their cross sections. Plane Stress and Plane Strain Equations Calculate the area of the right triangle with legs measuring 3 and 4 cm. Semiperimeter. The semiperimeter of a triangle equals half the sum of its sides. It is denoted with the letter s. Heron's Formula. Heron's formula is used to find the area of a triangle knowing the length of all three sides. Example The level of sophistication of this result is quite a bit higher than that of the rest of the papyrus (for example, the same papyrus gives incorrect formulas for some relatively simple plane areas), leading some people to suspect that either the Egyptians just stumbled into this particular formula, or else perhaps it was part of a more advanced ...
