1. Math Terms by: Peter and Sean

2. congruent 2 shapes that are the same

3. supplementary angle 180 together two angles that equal 180

4. intersecting, perpendicular. and parallel lines

5. adjacent angle an angle that shares a line

6. vertical angles the angle opposite to the other angle when two lines cross.

7. complementary angles 2 angles that equal to 90

8. Quadrilateral a shape with 4 sides

9. Square shape with 4 congruent sides and angles that are 90

10. Trapezoid a shape with 4 sides but only one set of parallel lines.

11. Rhombus A shape with 4 congruent sides

12. Rectangle 2 sets of parallel and congruent angles

13. Parallelogram A shape with 4 sides and the sides opposite from each other are parallel.

14. Parts of a Circle <--Radius ^ Diameter ^ || Radius: the distance from the center point to the edge of a circle Diameter: the distance from one edge of a circle to another going through the middle point.

15. Perimeter The distance around an object. To find it add up the sides Triangle Square Parallelogram w/ Rhombus Trapezoid Rectangle

16. Circumference the distance around a circle

17. Area of Triangle multiply the base times the height then divide it by 2. b x h=__, __/2=a

18. Area of a Rhombus or Parallelogram multiply the base times the height BxH=A

19. Area of a Square or Rectangle multiply the base times the height. BxH=A

20. Area of a Circle multiply pi (3.14) times the radius squared πr 2

21. Thales, Eudemus he discovered adjacent angles.

22. who he is He is a famous European mathmatican that had a very rich family.

23. he helps us today by letting us be smarter in math. helping us make more discoveries.

24. Real Life Square Perimeter An example would be if you had a square lawn you wanted surrounded by fence and one side was 7 feet, how would you find it?

25. Real Life Square Area Also if you wanted to plant 6 rows of flowers with 5 flowers in each row, how would you find it?

26. Real Life Circle Perimeter If you wanted to put Christmas lights around a round window, how would you find how much you need?

27. Real Life Circle Area Or if you are just fixing a window pane that had been broken, how would you figure how big of a pane you would need?

28. Angles in Everyday Objects Angles are in almost every object from corners in tables to the arches of bridges.
