Lines, lines, and More Lines! By: Ms. Rozelle 8 th 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 Project Lines, 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!
