Euclid: The Father of Geometry By: Lauren Oreto

Euclid’s Origin • Born in Greece in 325 B. C. • Family was wealthy • Raised in Greece; as a grown man, resided in Alexandria, Egypt • Graduated from Plato’s school in ancient Greece

The Elements • Basic Properties of triangles, parallelograms, and circles • Common Notions • Plane geometry • Solid Geometry • Number Theory

• Basic Properties Triangles- classified by their sides or angles

Basic Properties • Parallelogram- a quadrilateral with parallel opposite sides; rectangles, squares & rhombuses http: //www. mathopenref. com/rhombus. html

Basic Properties • Circle- shape where the edges are the same distance from the center all the way around

Common Notions If a=b and c=b, then a=c • Things that are equal to the same things are also equal to one another. • If equals are added to equals, they are also equal. • If equals are subtracted from equals, the remainders are equal. • Things which coincide to one another are equal to one another. • The whole is greater than the part. 2+6=8 394+888=1, 282 970 -672=298 If triangles ABC and EGF can be placed on one another and AB and EG are congruent.

Plane Geometry • Shapes on a flat surface; infinitely large but lie on a flat sheet • Deal with flat shapes like triangles, hexagons, squares, circles, etc.

Solid Geometry • Shapes that exist in more than one dimension (three dimensional geometry) • Deal with shapes like the cube, sphere, cylinder, pyramid, etc.

Number Theory Prime Numbers • Integer • Only divisible by 1 and itself • Ex: 3, 5, 7, 11, 13 Composite Numbers • Integer • Divisible by three or more numbers • Ex: 2, 4, 6, 27, 100
