- 12. Triangles • Triangles arealso a geometric shape • Having three corners • In all tri angles the sum of all angles 180 degrees
- 13. Angles • Angles areempty space between two surfaces . • Angles are calculated in degrees. • In this diagram angle is represented by
- 14. Shadow clock • Muslimresearcher used the idea about angles and made shadow clock or sun clock.
- 15. Right angle triangle •Right angle is invented by the people of Egypt . • They divided a rope into 12 pieces then they combine 5 pieces and 4 pieces and 3 pieces of rop
- 16. Right angle triangle •Then they join the corners . • Thus the right angle triangle invented
- 17. Balancing equation • Thisis a trick in which we find the value of unknown number. • In this unknown value is “x” and at last we find the value of “x” • This trick is introduced by Al Khwarizmi
- 18. Al Khwarizmi • Heis a founder of a branch of math's name algebra • Algebra have many benefits
- 19. Shapes of math's •these shapes are a major part of geometry. • A man who have a major part on research in this field is “Euclid”
- 20. Geometry and instruments •Scale and compass are use to draw straight line and circles. • When we combine these two instruments we will make many shapes of geometry.
- 21. Ellipse • This isa egg type shape in geometry it is called ellipse. • It has simple trick to draw
