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.
