PPT-3-1 Properties of Parallel Lines

LEQ 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. 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 By: Amethyst boyd. Parallel vs. Perpendicular. Parallel. Equal distance between lines from top to bottom.. Never intersect. Same slopes. EXAMPLES:. Perpendicular. Intersect forming 90 degree lines. On same plane. My math presentation of parallel and perpendicular lines… . And . mathiness. and history. These were from some ancient Roman or Greek guy. . H. is name was Euclid (for parallel). Though there was much talk about lines that crossed in a 90 degree way, the first time it was used in math was by a French philosopher named Cartesian.. Objective Learn to recognize parallel and perpendicular lines. . Parallel and Perpendicular Lines…. A . plane. is an infinite, flat surface. Lines in a plane that never meet are called . parallel Lines. 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). A point is an exact location in space.. You are here.. A true point has no length, no width, and no height.. In fact, you cannot see a true point.. A point is named by a letter.. P. Point P. Lines are 1-dimensional objects that have only length. Lines continue forever in both directions.. 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. 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.. Section 3.1 – Lines and Angles. I CAN identify relationships between figures in space.. I CAN identify angles formed by two lines and a transversal.. Key Vocabulary:. Parallel Lines. Skew Lines. Parallel Planes. Pgs. 26, 28, 30. Warmup. (pg. 23) . The measures of 2 Vertical Angles are 90 and (5x 10). Find the value of x.. The measure of an angle is twice the measure of its compliment. . What’s a Transversal? . Common Core Investigation 4: Geometry Topics. 4. 3. 2. 1. 0. In addition to level 3.0 and above and beyond what was taught in class, I may:. Make connection with real-world situations. Make connection with other concepts in math. 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 . Section 3.1 Big Ideas Geometry. Parallel Lines: Two lines that do not intersect and are coplanar. The symbol for parallel is || and is read “is parallel to”. So m||n reads “line m is parallel to line n”. 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..
