Grade 7 - Shape and Space

Standard 7.SS.3 - Practice identifying parallel, perpendicular and intersecting lines.

Included Skills:

Demonstrate an understanding of 2-D relationships involving lines and angles.
• Identify and describe examples of parallel line segments, perpendicular line segments, perpendicular bisectors, and angle bisectors in the environment.
• Identify, with justification, line segments on a diagram that are parallel or perpendicular.
• Investigate and explain how paper, pencil, compass, and rulers can be used to construct parallel lines, perpendicular lines, angle bisectors, and perpendicular bisectors.
• Investigate how paper folding can be used to construct parallel lines, perpendicular lines, angle bisectors, and perpendicular bisectors.
• Use technology to construct parallel lines, perpendicular lines, angle bisectors, and perpendicular bisectors.
• Draw a line segment perpendicular to another line segment and explain why they are perpendicular.
• Draw a line segment parallel to another line segment and explain why they are parallel.
• Draw the bisector of a given angle using more than one method and verify that the resulting angles are equal.
• Draw the perpendicular bisector of a line segment using more than one method and verify the construction.
• Use geometric constructions to create a design or picture, and identify the constructions present in the design.
