A slide show for Geometry

1. . Lines Angles Triangles Quadrilaterals Circles Geometry Guide

2. . Points Line segments Ray Lines Intersecting Lines Perpendicular Lines Parallel Lines Skew Lines Lines

3. . A line segment is a line that starts at a point and finishes at a point Line Segments

4. . A ray is a line that starts at a point and goes on forever Rays

5. . A line is something that never ends both ways Lines

6. . Skew lines are lines not in the same plane Skew

7. . Two lines that never cross and are in the same plane Parallel Lines

8. . Perpendicular lines are lines that intersect at a right angle (90 degrees) Perpendicular Lines

9. . Intersecting Lines are lines that cross at one point Intersecting Lines

10. . A point is a precise location in space. It is labeled with a letter. P I N K Points

11. . Acute Obtuse Right Straight Vertex/Vertices Complementary Supplementary Vertical/Opposite Adjacent Angles

12. . An acute angle is less than 90 degrees Acute

13. . An obtuse angle is more than 90 degrees Obtuse

14. . A Right Angle is exactly 90 degrees Right

15. . A Straight angle is a straight line that is 180 degrees Straight

16. . A vertex is a corner of an angle Vertex/Vertices

17. . Complementary is when two angles are added and equals 90 degrees Complementary

18. . Supplementary is when two angle are added and it equals 180 degrees Supplementary

19. . Vertical/Opposite is an angle on the opposite side of another Vertical/Opposite

20. . Adjacent is when an angle and another angle are next to each other Adjacent

21. . Right Obtuse Acute Scalene Isosceles Equilateral Sum of Internal Angles Perimeter Area Triangles

22. . A right angle on a triangle is Right

23. . An obtuse angle in a triangle is also more than 90 degrees Obtuse

24. . An acute angle in a triangle is also less than 90 degrees Acute

25. . Scalene means all the sides are different Scalene

26. . Isosceles is when two of the sides on a triange are the same Isosceles

27. . An equilateral is when all the angles on a triangle are equal Equilateral

28. . The sum of internal angles is the sum of all the angles is 180 degrees Sum of Internal Angles

29. . The perimeter is the sum of all sides Perimeter

30. . Area is the base and hieght of the triangle multiplied together Area

31. . Qualrilateral Trapezoid Parallelogram Rectangle Rhombus Square Area of a rectangle Area of a Square Area of a Parallelogram Area of a Trapezoid Quadrilateral

32. . A quadrilateral is a polygon with four sides and four angles Quadrilateral

33. . A trapezoid is 1 pairs of parallel lines and two congruent sides Trapezoid

34. . The area of a trapezoid is how much cubes you can fit inside by doing base times height Area of a Trapezoid

35. . A parallelogram is 2 pairs of parallel lines and 2 congruent sides Parallelogram

36. . The area of a parallelogram is how much cubes you can fit inside by base times height Area of a Parallelogram

37. . A Rectangle is two sets of parallel and congruent lines Rectangle

38. . The Area of a Rectangle is how much cubes fit inside by doing the length times width Area of a Rectangle

39. . A Rhombus is just like a rectangle with two sets of parallel and congruent lines Rhombus

40. . Now a square is different all the sides are congruent and parallel Square

41. . The area of a square is really easy and the same as a rectangle all you have to do is one number squared Area of a Square

42. . Chord Diameter Radius Sector Circumference Area of a Circle Circles

43. . A chord is from one point connected to another in the circle Chord

44. . The diameter of a circle is how long it is from one side to another Diameter

45. . An arc on a circle is the distance from one point to the other on the outside edge Arc

46. . The radius of a circle is how far it is to the middle of the circle Radius

47. . A Sector is a piece of the circle Sector

48. . The circumference of a circle is the distance around the circle and you get it by diameter times pie Circumference

49. . The area of a circle is the space inside by doing radius squared times pie Area of a Circle

50. . Hexagon Octogon Pentagon Regular Polygon Other Polygons

51. . A hexagon is a polygon that has 6 sides Hexagon

52. . A Octogon is also a polygon but it has 8 sides Octogon

53. . A pentagon is just like the rest but with 5 sides Pentagon

54. . A regular polygon is different from other polygons because regular polygons have different sizes and sides Regular Polygons
