  2. 2. Geometry Journal # 1 Point, Line and Plane Collinear and Copplanar points Ray,line and segment relathionship Questions 1-3 Next 4 problems
  3. 3. Point, Line and Planes Whats a Point ? Whats a line ? Whats a plane The name for a location represented with a dot. It has no specific size you write it as a capital letter in this case A,B Examples here A and B are both points B A A line is a straight path that has no thickness and extends forever unles stoped by an endpoint. You write it as a lower case letter or two points on a line example e or <-------> XY Example of a line A plane is a flat surface that has ni thickness and extends forever. Here is where your points and lines go. You write it as a script capital letter or 3 points together R or ABC C
  4. 4. Collinear and Coplanar points Collinear points are the points located inside a line,ray or segment. Copplanar points are the points located inside the plane but they are like free points which are not part of a line. Both are similar because the are inside a plane and they are points or coordenates. But they are different because one from a line and the other one is free inside the plane B A A and C are collinear and B,A,C coplanar C
  5. 5. Ray,line and segment relathionship Ray Segment Line How do they relate? A line with one standing point and then extending forever into that direction You write it as ----  RS A segment,fraction,part of a line. It consits of 2 points between the line. You write it as ------- MN R S M N A line is a straight path that has no thickness and extends forever unles stoped by an endpoint. You write it as a lower case letter or two points on a line example e or <-------> XY They all relate because all have points and are parts of a line. Segments and Rays have endpoints. Segments are parts of lines and Rays go towards an nonstoping line.
  6. 6. Questions 4-8 Intersections Postulate,Axiom and Theorem Ruler postulate Segment addition postulate
  7. 7. Intersections An intersection is the set of all points that two or more lines have in common. Its the point where lines cross and it marks a difference because it the only time where this two lines can join. Examples Inter state 44 and Inter state 45 join at Km 44 Carretera a el Salvador The Greenwhich line intersect the tropic of capricorn 44 45 Line A Intersects with line B A B
  8. 8. Postulate,Axiom and Theorem Postulate or Axiom: Any rule we don't have to prove it's a fact Theorem: A statement that has been proven They are all similar because they are proven (facts) they state reality and explain. They dont need to be proven because the answer to them is always the same 2+2=4 always……
  9. 9. Ruler postulate To measure a segment you use a ruler and substract the values of the end points. Ruler 1 2
  10. 10. Segment addition postulate If 3 collinear points with B inbetween A and C then AB+BC=AC Examples 1.) 2.) 3.) 1 5 9 A B C AB=4 BC=4 so AC=8 10 12 18 AB=2 BC=6 so AC=8 1 10 11 AB=9 BC=1 AC=10

  13. 13. Pythagoream Theorem <ul><li>a2+b2=c2 It is used to find the hypotenuse of a right triangle.
