Are you looking for a fun way to help students practice identifying parallel and perpendicular line pair in a complex polygon? My fourth graders were successful in identifying relationships in a single pair of lines, but once they saw them in the context of a polygon they were overwhelmed. The way we got over that hurdle was a good old connect-the dot page, with some relevant practice work attached to their "mystery picture." The follow up questions require students to "color code" some of the lines and fill in the appropriate vocabulary word (perpendicular or parallel).
This page even comes with an extension page in which students will draw their own robot and color code the parallel and perpendicular lines.
