3-3 Proving Lines Parallel: Transcript


Students will be able to Determine whether two lines are parallel Write flow proofs Define and apply the converse of the theorems from the previous section Objectives You can use certain angle pairs to determine if two lines are parallel. Unlike sequential algorithms parallel algorithms cannot be analyzed very well in isolation One of our primary measures of goodness of a parallel system will be its scalability Scalability is the ability of a parallel system to take advantage of incr 8.G.5. Essential Question. ?. What can you conclude about the angles formed by parallel lines that are cut by a transversal?. Common Core Standard. :. 8.G ─Understand . congruence and similarity using physical models, transparencies, or geometry software.. Angle Relationships . Parallel Lines are j & k. Transversal is l. Corresponding Angles. “Corresponding” means “matching”, so corresponding angles are the ones at the same location at each intersection.. Parallel Lines and Transversal. Alternate interior angles are congruent if the lines are parallel. Corresponding angles are congruent if the lines are parallel. Given the picture list all corresponding angles, list all Alternate interior angles (assume lines are parallel). Parallel Lines. Intersecting Lines. Perpendicular Lines. Perpendicular Lines. Parallel Lines. These lines have the same slope. But not the same y-intercept. These lines have the same slope . and the same y-intercept. Dr Susan Cartwright. Dept of Physics and Astronomy. University of Sheffield. Parallel Universes. Are you unique?. Could there be another “you” differing only in what you had for breakfast this morning?. L.E.Q. What special angles are created by two lines cut by a transversal and how are they related?. Remember:. What would you call two lines which do not intersect?. Parallel. A solid arrow placed on two lines of a diagram indicate the lines are parallel.. Line. Line- a straight path that goes in two directions without ending.. A. B. AB. Read: “Line AB”. Ray. A ray has one end point and goes on forever in only one direction.. CD. Read: “Ray CD”. Lines & planes. Parallel lines. : two lines in the same plane that don’t intersect.. Skew Lines. : two lines . not. in the same plane that don’t intersect.. Parallel Planes. : two planes that don’t intersect.. By,. Michael . Thiel. and Lauren . Larar. . . What Family?. First, you must identify what family the quadrilateral falls under.. Parallelogram. , . Trapezoid. ,. . quadrilateral.. Proving that a quadrilateral is a Rectangle. Chapter 3. Parallel Lines & Transversals. Section 3.1. Vocabulary. Parallel lines. Parallel planes. Skew lines. Transversal. Consecutive interior angles . Alternate interior angles. Alternate exterior angles. Algebra 1 Unit 5: Writing equations of lines. Parallel Lines. What are parallel lines?. Parallel lines are two lines that never intersect each other.. Where have you seen examples in real-life?. Lines on a road. i.e. . they do not meet).. What is the shortest distance between them?.  .  .  .  . Also find the co-ordinates of . and . ..  . shortest distance. must be perpendicular to both lines.. Let . Then . Draw a third line parallel to, and equidistant between, the first two lines.. Draw a two more lines parallel to the three lines so that you now have five equally spaced lines.. Decide which base pair you will draw, and on which side you will have the purine base and on which side you will have the pyrimidine base..
