PPT-3.1 Identify pairs of lines & angles

Lines amp planes Parallel lines two lines in the same plane that dont intersect Skew Lines two lines not in the same plane that dont intersect Parallel Planes two planes that dont intersect. Sections 3-1. What you’ll learn. How to identify the relationships between two lines or two planes. How to name angles formed by a pair of lines and a transversal. Vocabulary. . Parallel lines. Parallel planes. CH 3-Perpendicular & Parallel Lines. Geometry I. Takes you to the main menu. Takes you to the help page. There are other buttons explained throughout the PowerPoint. Navigating the PowerPoint. Main Menu. Created By: 2BrokeTeachers. A Parade of Four-Sided Polygons. Quadrilaterals. There are many different types of quadrilaterals. We identify quadrilaterals using their sides and angles. . Side. Angle. Let’s Review…. 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.. Vertical angles. Supplementary. Complimentary. Adjacent. Types of Angle PAIRS. Vertical angles. Supplementary. Complimentary. Adjacent. Why are the numbers the same COLOR?. Identify Angle Pairs. True or False?. 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.

Think about . number patterns . 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.. The following presentation is a geometry lesson for fifth to sixth grade students. The slides show photographs of different houses and an explanation or definition of geometry terms. . The students are also shown an example of each term that has been . 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? . Angles of Triangles Objectives Find angle measures in triangles. Key Vocabulary Supplementary Angles Complementary Angles Exterior angles Interior angles Additional Vocabulary Theorem - Mathematics. a theoretical proposition, statement, or formula embodying something to be proved from other propositions or formulas. 2. a rule or law, especially one expressed by an equation or formula 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”.
