Parallel & Perpendicular Lines: Transcript
Chapter 3 Parallel Lines amp Transversals Section 31 Vocabulary Parallel lines Parallel planes Skew lines Transversal Consecutive interior angles Alternate interior angles Alternate exterior angles. 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. Parallel and Perpendicular Lines. Perpendicular lines. are two lines that intersect to form a 90º. . angle. . Parallel and Perpendicular Lines. Parallel lines. are two lines that, if extended indefinitely, would never cross or touch. Ms. Andrejko. Real World. Vocabulary. Equidistant-. the distance between two lines measured along a perpendicular line to the lines is always the same. The distance between a line and a point not on the line is the length of the segment . PART III. PARALLEL UNIVERSE. When two numbers are the same in mathematics, we say they are. equal.. When two figures in mathematics are exactly the same, we say they are . congruent.. Technically, . and a Transversal. Vocabulary. Parallel lines. : Lines in the same plane that have the same slope and never intersect. . Transversal. : A line that intersects two or more parallel lines.. Interior Angles. 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.. Find some examples of horizontal lines. Vertical. Think of some examples of vertical lines. Parallel. Find some examples of parallel lines. Perpendicular. Find some examples of perpendicular lines. What sort of angle is this?. 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”. 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. Warm Up. Construct each of the following.. 1.. . A perpendicular bisector.. 2.. An angle bisector.. 3.. Find the midpoint and slope of the segment . (2, 8) and (–4, 6).. . Prove and apply theorems about perpendicular bisectors.. Geometry. Chapter 3. This Slideshow was developed to accompany the textbook. Larson Geometry. By Larson. , R., Boswell, L., . Kanold. , T. D., & Stiff, L. . 2011 . Holt . McDougal. Some examples and diagrams are taken from the textbook.. 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. Pencil. Handouts you picked up. Work silently & independently. DO NOW!:. . Fill in . the blank with . always. , . sometimes. , or . never. .. If . two planes intersect, then they intersect . at a line.. 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..
