Lines, lines, and More
Lines!
By: Ms. Rozelle8th Grade Math
Intersecting VS Perpendicular
═Are they the same??═Noooo!═Perpendicular lines intersect at a
right angle! (90 degrees)═ Intersecting lines cross each other.═Are all perpendicular lines
intersecting lines?═Are all intersecting lines
perpendicular lines?
Skew VS Coplanar
═Skew lines do not lie on the same plane!
═Coplanar lines do!═Can skew lines also be intersecting or
perpendicular lines?═Can coplanar lines also be
intersecting or perpendicular lines?
Parallel VS Coincidental
═Parallel lines lie in the same plane but never intersect!
═Coincidental lines have equivalent linear equations and overlap at EVERY point!
═Coincidental = One line on top of the other
═Can skew lines also be coincidental lines?
═Can parallel lines also be skew lines?
Equilateral VS Isosceles VS Scalene
═Equilateral Triangle?? All sides are equal!
═ Isosceles Triangle?? Triangle with two equal sides! Angles opposite the equal sides are also equal.
═Scalene Triangle?? Has three unequal sides!
Geometry Map ProjectLines, Angles, & Triangles!
• Your task is to design a map that includes several different kinds of lines, angles and triangles. You can choose your own theme for your map. Your map can be of a town, your neighborhood or a made up place. It must however include the following:
• - Title of your town/neighborhood/made up place• - Two sets of streets that are parallel• - Two sets of streets that are perpendicular• - Two sets of streets that are Coincidental Lines • - One street that intersects another street to form an obtuse angle• - One street intersects another to form an acute angle• - One street that is a line segment• - One street that is a line • - One street that is a ray• - An ice cream parlor in the shape of an equilateral triangle• - A Pool that is in the shape of a scalene triangle• - A Pizza Place in the shape of a Isosceles triangle
• Once your map is completed you are to write out five directions from one place to another. Each direction must have one of these terms: parallel, intersecting or perpendicular. These directions should be able to get your teacher and classmates from one place to another without getting lost!
