3. Point POINTS POINT J

A point is a precise location in space. It is labeled with a letter.

4. Planes

Flat Surface that needs three points

5. Lines 6. Lines

A figure that goes through two points traveling forever in both directions.

7. Line Segment

A straight line that can be measured.

8. Ray

Starlight or a straight line that continues from a point

9. Properties of Lines 10. Intersecting

Two linesthat cross at a point.

11. Perpendicular

Intersecting at right angels.

12. Parallel

Never crossing lines in the same plane.

13. Skew

Lines that aren't in the same plane.

14. Angels 15. Types of Angles 16. Acute

An angle that is less than 90 degrees

17. Obtuse

An angle that is larger than 90 degrees.

18. Right

An angle that is 90 degrees.

19. Straight

A straight angle that is 180 degrees.

90 90 20. Vertex/ Vertices

The small corner of any angle.

21. Complementary

Two angles when they are added equal 90degrees.

60 30 22. Supplementary

Two angles when they are added equal 180 degrees.

23. Vertical/Opposite

Two angles that are across from each other.

24. Adjacent

Two angles that have a connected line.

25. Triangles 26. Right

A triangle is were 2 lines meet that form 90 degrees.

27. Obtuse

A triangle that has 2 lines that equal more than 90 degrees.

28. Acute

A triangle thats two lines don't add up to 90 degrees.

29. Scalene

A triangle that has no equal sides.

30. Isosceles

A triangle that has two congruent sides.

31. Equilateral

The triangle has all sides the same measurement.

32. Sum of Internal Angles

This is when you add two or more angles together in a triangle to get 180 degrees.

60 60 60 33. Area of a Traingle

The area of a triangle is base times height.

34. Quadrilaterals 35. Perimeter

The sum of the outside of an object.

Twenty Twenty ten ten 36. Area

How big or small the inside of a three dshape is.

37. Quadrilaterals

These are a 4 sided shape.

38. Trapezoid

A shape that has 2 parallel sides.

39. Parallelogram

A shape that has parallel sides on the opposite end and they are also congruent.

40. Rectangle

A parallelogram with 4 right angles.

41. Rhombus

A shape that looks like a diamon but doesn't have any right angles.

42. Square

A square is a shape that has 4 equal sides and it has 4 right angles.

43. Area of a Rectangle

The area of a rectangle is the length times width or how many blocks are able to fit in it.

15in 15in 44. Area of a Square

How long the width is X the length or how many blocks total can fit in there.

12 inches 12 inches 45. Area of a Parallelogram

This is base times height.

46. Area of a Trapezoid

• The area of this is the space inside the shape.

47. Circles 48. Chord

• A segment connecting two lines on a circle.

A B 49. Diameter

• A chord that passes through the middleof the circle.

C 50. Radius

• The distance from the center of thecircle to the outside edge.

51. Sector

• A piece of the area.

52. Circumference Distance around a circle. 53. Arc The distance around the outside edge between two points. 54. Area of aCircle The space inside of a circle. Blue = area. 55. Other Polygons 56. Hexagon A six sided shape. 57. Octagon An eight sided shape. 58. Regular Polygon All the sides are congruent.
