An angle is formed when two rays share a common endpoint. Want to know more about angles? There are a lot of terms in this lesson. You might have to watch it two or even three times to make sure you understand all the terms. I recommend...

Here is a geometry lessonwhich invites learners to create models using their knowledge of lines, segments, rays, and angles. This lesson reinforces geometric vocabulary and concepts through practical application, it also includes...

Is it a line, line segment, ray, or angle? Identifying geometric figures is the focus. In addition to identification, learners recognize right angles or tell if an angle is less than or greater than a right angle. They tell if lines are...

Upper graders solve ten multiple choice problems about angles and measuring angles.

In this recognizing geometric figures worksheet, students read descriptions, draw, label, and write the names and symbols for basic geometric figures. Students solve thirteen problems.

An angle is formed when two rays share a common endpoint. Want to know more about angles? There are a lot of terms in this lesson. You might have to watch it two or even three times to make sure you understand all the terms. I recommend...

A ray is a line that begins at an identified point and then goes on forever in one direction. The identified point is called the endpoint. There needs to be another identified point on the line to be able to identify the line as a ray....

In this ray worksheet, learners complete a ten question crossword puzzle with words that pertain to rays. There is a word bank provided.

This art lesson plan seems simple enough. As a way to introduce radial symmetry, spokes, or rays, learners create an artistic representation demonstrating radial symmetry. They stick a variety of letter stickers on their paper starting...

In this parts of line worksheet, students solve and complete 12 various types of problems. First, they find the length of the indicated line segments. Then, students determine the lengths of the line segments listed.

Upper grade pupils identify diagrams, checking the appropriate box for each. A reference web site is given for additional activities.

Learners first name angles in three ways, then classify them as acute, obtuse or right angles. Good practice when introducing the concept of different types of angles.

High schoolers investigate harmonic conjugates using Cabri Software or the Ti Calculator to analyze harmonics. They explore different angles measurements as they move their circles around and solve problems.

Students study shark and ray adaptations that have helped their survival.  In this animal adaptations lesson students view a video and work in groups to research specific types of sharks and rays.

For this line worksheet, students sketch 6 lines, line segments, and rays.  Students sketch examples of a line, line segment, and ray.

Third graders explore angles. In this geometry activity, 3rd graders identify and define acute, obtuse, and right angles. Students form angles with their bodies, find angles in picture books, and record angles found outside in their...

In this basic skills worksheet, students draw lines, segments, and rays according to given instructions. This four-page worksheet contains 20 problems. Answers are provided on the last two pages.

Learners discover the different types of mirrors, their properties and some of their applications. They have already been introduced to some of the properties of light and have already experienced some of the different types of mirrors...

Eighth graders complete a unit of lessons on basic geometry concepts. They participate in a variety of activities, culminating in a project that involves publishing a booklet or a poster that presents the major geometry concepts from the...

In this line and angles activity, learners explore basic geometry vocabulary.  They classify polygons.  Students determine the area and perimeter of given shapes.  They examine the parts of a circle, find volume and surface area of...

For this line, ray, and line segment worksheet, students fill in the twenty blanks with the appropriate terms.  The solutions are provided.

In this geometry: identifying lines and rays worksheet, student answer six multiple choice questions identifying lines, line segments and rays.

In this geometry instructional activity, students identify diagrams as either lines, line segments, rays or points, write the definition of each and match it to its diagram. 

In this geometry worksheet, 5th graders label the two figures shown. Worksheet reviews and provides examples of a point, parallel lines, angles, rays, line segments, and perpendicular lines.
