- 1. Philip's Geometry Guide to Success 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. It is labeled with a letter.
Point a Point b Point c Point d 4. Line Segments
- A line line that starts at one point and ends at another
5. Ray
- A line that starts at a point and keeps going past the other
6. Intersec t ing
- Two lines that meet at a point and do not make 90 degree angles
7. Perpendicular
- The lines intersect at right angles
8. Parallel
- Lines that never cross and are on the same plane
9. Skew
- Lines that are not on the same plane
10. Plane
- A flat surface that goes on forever in all directions and is defined by three points
P 11. Angles
- acute
- obtuse
- right
- straight
- vertex/vertices
- complementary
- supplementary
- vertical/ opposite
- adjacent
12. Acute
- An angle that is less than a 90 degree angle
13. Obtuse
- An angle that is more than a 90 degree angle
14. Right
- An angle that is exactly 90 degrees
15. Straight
- An angle made up by two 90 degree angles
16. Vertex/Vertices
- The point where the lines to make the angle meet
17. Complementary
- Two angles that if you add them together you will get 90 degrees
4545 18. Supplementary
- Two angles that if added together you get 180 degrees
110 70 19. Vertical/Opposite
- An angle that is opposite to the same angle
20. Adjacent
- An angle that is sharingthe same vertex with another angle
F D E C Angle DFE Angle EFC 21. Triangles
- Right
- Obtuse
- Acute
- Scalene
- Isosceles
- Equilateral
- Sum of internal angles
- Perimeter
- Area
22. Right
- If the largest measure of the triangle is 90 degrees
23. Obtuse
- When the largest angle of the triangle is more than 90 degrees
24. Acute
- When the largest angle of the triangle is less than 90 degrees
25. Scalene
- When all the sides of the triangle are not equal
26. Isosceles When there are two sides of the triangle that are the same measure 27. Equilateral
- When all the sides of the triangle have the same measure
28. Sum of internal angles
- All the sides in the triangle add up to 180 degrees
60 60 60 29. Perimeter
- The sum of all the sides of the triangle
50 70 60 50+70+60=180 30. Area
- When you multiply length times width and then divide it by 1/2.
30 60 60 times 30 divided by 1/2 31. Quadrilaterals
- Quadrilaterals
- Trapezoid
- Parallelogram
- Rectangle
- Rhombus
- Square
- Area of a rectangle
- Area of a square
- Area of aparallelogram
- Area of atrapezoid
32. Trapezoid
- A figure that has 1 set of parallel sides.
33. Parallelogram
- A figure that has 2 sets of parallel sides
34. Rectangle
- A figure that has 2 parallel sides and all the angles are congruent
35. Rhombus
- A parallelogram that has no congruent sides
36. Square
- A parallelogram that has 2 parallel sides and all the angles are congruent
37. Area of a rectangle
- You multiply length times width
L W L times W= A 38. Square
- You multiply length times width
L W L times W = A 39. Area of a Parallelogram
- You multiply length times width
8 12 8 times 12= A 40. Area of a Trapezoid
- You put 2 trapezoids together to make arectangle and ad the top to the bottom then multiply it to width and divide by 2.
W L 4+ 6= 10 divided by 2 4 41. Circles
- Chord
- Diameter
- Arc
- Radius
- Sector
- Circumference
- Area of a Circle
42. Chord
- The chord is the longest line segment in the circle
43. Diameter
- The diameter is the radius times 2
44. Arc
- The arc is the distance on the outside edge of the circle
45. Radius
- The radius is diameter divided by 2
46. Sector
- The sector is a piece of the area.
47. Circumference
- The distance around the circle (C= D times 3.14)
48. Other Polygons
- Hexagon
- Octagon
- Pentagon
49. Hexagon
- The hexagon is a polygon with six sides
50. Octagon
- The octagon is a polygon with eight sides
51. Pentagon
- The pentagon is a polygon with five sides
52.
