  • 3. Points
    • A point is a precise location in space. It is lab bled with a letter.
    Point f f
  • 4. Line segment
    • A part of a line.
  • 5. Line
    • A never ending line
  • 6. Ray
    • A line that never ends but only gos one way
  • 7. Intersecting
    • Lines that cross
  • 8. Skew
    • Lines that are not on the same plane
  • 9. Parallel
    • Perpendicular lines that never cross
  • 10. Angles acute, obtuse, right, straight, vertex/vertices, complementary, supplementary, vertical, opposite, adjacent
  • 11. Acute
    • An angle that is less than 90 degrees.
  • 12. obtuse
    • An angle over 90 degrees
  • 13. right
    • A 90 degree angle
  • 14. straight
    • A 180 degree angle
  • 15. vertex/verticies
    • The point were to angles meet
  • 16. complementary
    • To angles that are complementary add up to 90 degrees
    10 degrees 80 degrees
  • 17. Supplementary
    • To angles that add up to 180 degrees
    90 degrees 90 degrees
  • 18. vertical
    • Vertical is the opposite angle
  • 19. opposite
    • To different angles
    90 degree 90 degrees
  • 20. adjacent
    • An angle that shares a vertex with 2 other angles.
  • 21. triangles right, obtuse, acute, scalene, isosceles, equilateral, sum of internal angles, perimeter, area of a triangle
  • 22. Right triangle
    • A triangle which biggest angle is 90 degrees
  • 23. Obtuse triangle
    • A triangle which has the biggest angle over 90 degrees
  • 24. Obtuse triangle
    • A triangle which has the biggest angle over 90 degrees
  • 25. Acute triangle
    • A triangle with all angles less then 90 degrees.
  • 26. Scalene
    • A triangle with no equal sides.
  • 27. Isosceles
    • A triangle with to congruent sides.
  • 28. Equilateral
    • A triangle with all equal angles
  • 29. Sum of Internal Angles
