Curated OER
Concurent Circles II
In this geometry worksheet, students draw a shape based on the directions. They tell the reasons the four resulting circles are concurrent. A sample drawing is included.
Curated OER
Segments
For this line segments worksheet, students complete problems involving points, longer and shorter segments, intersections, and more. Students complete 5 problems total.
Curated OER
Map Making Project
Students identify and draw parallel, intersecting, and perpendicular lines and line segments. In this lines lesson plan, students draw a map with avenues and streets by drawing these lines.

Lines-Online Quiz
In this math worksheet, students identify pairs of lines as parallel, intersecting, perpendicular, or none of the above. Each problem is presented as a drawing of two lines. The kids click in the box that tells their choice of answers....
Curated OER
Parallel and Perpendicular Lines
Fourth graders examine parallel, perpendicular and intersecting lines. They create a drawing using examples of each type of line. They color code and explain the characteristics of specified lines.
Curated OER
Identifying Parallel and Perpendicular Lines
Students explore basic geometry. In this geometry lesson, students study points and lines that exist in flat planes. Students investigate parallel and perpendicular lines.
Curated OER
Rotations
Young scholars discuss the concepts of reflection, rotation, and translation. In this rotation activity, students investigate rotations through examples on an overhead projector. No additional worksheet or student assignment is included.
Curated OER
Parallel, Intersecting, and Perpendicular Lines
In this geometry lines worksheet, 10th graders solve 9 different problems related to various types of lines found in geometry. They classify each pair of lines shown as either parallel, intersecting, or perpendicular lines.
