Planer Geometry Guide
- 1. Ryan's Geometry Guide Lines Angles Triangles Quadrilaterals Circles
- 2. Lines Points Line Segments Rays Lines Intersecting Lines Perpendicular Lines Parallel Lines Skew Lines
- 3. Points A point is a precise location in space. Its is labeled with a letter. Point R Point T R T
- 4. Line Segments A line segment is a line that stops at both ends at a point.
- 5. Rays A ray is a line that ends at a point on one side and dosn't end at the other.
- 6. Lines A line never ends on both sides no mater what.
- 7. Intersecting Lines Two lines crossing each other.
- 8. Perpendicular Lines Two lines intersecting at 90 degrees.
- 9. Parallel lines Two lines that never cross and have the same plane
- 10. Skew Lines Lines that are not in the same plane
- 11. Angles Acute Obtuse Right Vertex/Vertices
- 12. Acute Acute is less then 90 degrees .
- 13. Obtuse Obtuse is more then 90 degrees .
- 14. Right A right angle is 90 degrees always.
- 15. Straight Straight angle is a straight line.
- 16. Vertex/Vertice Vertex/vertices is the middle part of two lines.
- 17. Complementary Complementary is all the numbers togeater to get 90 degrees. 50 degrees 40 degrees
- 18. Supplementary Supplementary is two lines that makes 180 degrees. 50 degrees 130 degrees
- 19. Vertical/Opposite Vertical and opposite are two lines connecting.
- 20. Adjacent Adjacent is using more then one line
- 21. Triangles
- 22. Right Triangle Right triangles have 90 degrees on onee side.
- 23. Obtuse Triangle An obtuse triangle has a side that is more than 90 degrees.
- 24. Acute Triangle An acute triangle has one or more sides that are less than 90 degrees.
- 25. Scalene Triangle A scalene triangle has no equal sides
- 26. Isosceles Isosceles is a triangle with two sides with the same degrees and one doesn't. 45 degrees 40 degrees 40 degrees
- 27. Sum of angles The sum of the angles are all the angles added together. 40 degrees 80 What is this angle ?
- 28. Perimeter The perimeter is the area around the shape.
- 29. Quadrilaterals
- 30. Quadrilateral A shape with no congruent sides.
- 31. Trapezoid A trapezoid has two congruent sides.
- 32. Parallelogram A parallelogram is a shape with two parallel sides.
- 33. Rectangle A rectangle has two congruent sides and it has other two congruent sides but smaller.
- 34. Rhombus A rhombus is like a diamond.
- 35. Square A square is a four sided shape and all sides are the same size.
- 36. Circles
- 37. Chord A line that goes throw a circle to the other side of the circle.
- 38. Circumference The distance measurement around the outside of the circle.
- 39. Octagon A octagon is a eight sided shape.
- 40. Hexagon A hexagon is a shape with six sides.
