Geometric mean involves roots and multiplication, not addition and division. You get geometric mean by multiplying numbers together and then finding the. root is equal to the amount of numbers you multiplied. Geometric mean is useful in many circumstances, especially problems involving money.
Number of electron pairs Shape Bond angles Examples Two linear 180o Ag(NH3)2+, CO2 Three Trigonal planar 120o CH2=CH2, BF3 Four tetrahedral 109.5o CH4, NH3*, H2O Six octahedral 90o SF6, Fe(CN)63– We can use advanced EPR theory to predict the shape of any molecule or ion.
Geometry Formulas - Calculating the length, perimeter, area and volume of different geometric figures and shapes. The Plane Geometry deals with shapes such as circles, triangles, rectangles, square and more. Whereas, the Solid Geometry is concerned in calculating the length, perimeter...

In geometry, 3D Shapes are the solid objects that has three dimensions- length, width and height. Unlike flat 2D shapes like squares and rectangles , 3-D shape has depth or thickness. Some real life examples of 3 D shapes are rubik’s cube, ice cream cone,or an orange. 3D shapes are introduced in Grade 6.
