Geometry

• Geometry is the branch of mathematics that deals with shapes, angles, dimensions and sizes of a variety of things we see in everyday life
• Geometry is derived from Ancient Greek words – 'Geo' means 'Earth' 
•  'metron' means 'measurement'.
• Area - The space occupied by a flat shape or the surface of an object.
• Perimeter - Continous line forming the boundary of a closed geometrc figure.
• Circumference - Distance around the edge of a circle or sphere.
• Surface Area - Total area of all surfaces of a 3-dimensional obejct.
• Volume - Amount of three-dimensional space enclosed within a solid object. The amount can be held, as measured in cubic units.
• Area and Perimeter of a Square.
