The world is made Of many shapes Plus all the patterns They create And when we measure What we see That's when we do Geometry Geometry Oh geometry It’s how we measure What we see Geometry Oh geometry Now let's learn Geometry Triangles have Just three sides And three angles You find inside When equal sides Are all around Equilateral Is what you've found One right angle Like a square A right triangle Is what’s there Two equal sides But not all three That is called Isosceles When three unequal Sides are seen That triangle Is called scalene Add all the angles And you’ll see It always equals One-eighty The world is made Of many shapes Plus all the patterns They create And when we measure What we see That's when we do Geometry Geometry Oh geometry It’s how we measure What we see Geometry Oh geometry Let's learn some more Geometry Quadrilaterals Have four sides With four little angles Tucked inside Parallelograms Have opposite sides Equal in length Same angles inside One type’s a square A perfect sight With sides all equal Angles all right Rectangles too So say their name When there are four right angles And two sides the same Rhombus is next With the same four sides And its opposite angles The same inside Trapezoids Are awkward and strange Two sides stay parallel The rest can change Kites have two pairs Of equal-length sides Arranged like a toy You fly outside Group them all In one big tree The quadrilaterals Of geometry Rhombuses, rectangles And also squares Can be parallelograms So you’re aware A square is a rectangle It’s a rhombus too But the inverse is NOT also true The world is made Of many shapes Plus all the patterns They create And when we measure What we see, That's when we do Geometry Geometry Oh geometry It’s how we measure What we see Geometry Oh geometry And still there's more Geometry Five sides make a pentagon Six makes a hexagon Seven sides a heptagon Eight make an octagon Nine sides Form a nonagon Ten sides A decka-gon Circles stand Apart from these No straight sides Or angles, please Just a curved line All around Equal distance Can be found From the center To the edge That's the radius I pledge Across the middle, Through the dot The diameter Is what you've got The world is made Of many shapes Plus all the patterns They create And when we measure What we see That's when we do Geometry Geometry Oh geometry It’s how we measure What we see Geometry Oh geometry Now just a bit more Geometry Shapes can be Cut into parts That’s where Learning fractions starts Split just once Right down the middle That’s one half There is no riddle Just like having Just one mitten One over two Is how it’s written And on and on For thirds and fourths And fifths and sixths And many more Cut in three Each part's one-third Cut in four One-fourth's the word As parts get smaller Numbers climb That's how fractions Work each time The world is made Of many shapes Plus all the patterns They create And when we measure What we see That's when we do Geometry Geometry Oh geometry It’s how we measure What we see Geometry Oh geometry And now you know Geometry Geometry Oh geometry Now you know Geometry
