In this perpendicular lines practice worksheet, students find and list examples of perpendicular lines at home, at school, and outside.

Fifth graders study repeated lines and colors as they create lines of symmetry. In this math and visual arts lesson, 5th graders examine works of art by Michael Gregory and Martin Puryear to look for colors, lines, and shapes. They use a...

Explore how lines of symmetry help define different categories of quadrilaterals. Looking at a square, rectangle, trapezoid, and parallelogram, young mathematicians discover that each shape has its own, unique symmetry. Encourage your...

Learners analyze the examples of lines and angles. They label 16 pictures of lines or angles with the correct term.

Why was the obtuse angle upset? Because it was never right! A valuable resource is loaded with background information on types of angles and lines. Learners review the characteristics of parallel, perpendicular, and intersecting lines,...

Upper graders identify locations within environments. In this location elements activity, learners complete activities to help them locate various points, lines, and planes within a given environment. They sort lines to identify them as...

What can symmetry tell us about triangles? After looking at four examples, learners will come to realize that lines of symmetry are different for equilateral, isosceles, and scalene triangles. Use this guided practice activity as an...

Use the alphabet as a tool for teaching your class about geometric figures. Break apart capital letters into line segments and arcs. Classify angles as right, acute, or obtuse. Identify parallel and perpendicular lines. An excellent...

Challenge your class to construct a definition for trapezoids. Looking at four examples and four non-examples, students individually create definitions and use them to classify an unknown shape. Allow for small group and whole-class...

Parallel lines never intersect. That's right, NEVER! They are in the same plane but never touch. The instructor illustrates many types of lines and shows you how parallel lines don't ever cross.
