Take one angle and get two. The presentation provides the steps required to copy and bisect an angle. Pupils follow the steps to create the two constructions. They create their own foldable to keep track of the steps for each construction.

Can you define that basic figure? Building upon the undefined terms in geometry, the lesson defines basic geometry figures. The resource defines line segment, ray, angle, perpendicular lines, and parallel lines.

Geometry begins with a point. The video introduces the concepts of points, lines, and planes. Using diagrams, the presenter includes how to name the objects along with how to write the names. Previewing the concept of 3-D space ends the...

Angle ABC is not the same as angle BCA, but it is the same as angle CBA. Help your classes understand naming conventions of angles and, more importantly, the importance of naming angles correctly. Scholars practice the parts of the angle...

Take a look at the definition from a different angle. The short assessment asks pupils to develop a precise definition of an angle. The scholars draw and label and angle to assist with the definition.

Investigate dilations to learn more about them. The second segment in a series of 16 provides a discussion of properties of dilations by going through examples. The problem set provides opportunities for scholars to construct dilations.

Mathematicians use notation for efficiency, so make your classes more efficient! The instructor explains the definition and notation for key elements of geometry such as points, lines, and planes. This is the 37th lesson is a series of 40.

Study concave and convex mirrors with an in-depth slideshow presentation. Slides contain term definitions as well as labeled diagrams.

This presentation offers an in-depth look into linear equations and inequalities. Here, teacher-orientated slides provide detailed information to share with your mathematicians, while student-oriented slides detail activities that...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Set your pupils up to start on geometry by teaching them some introductory terminology. Pupils learn the terms by reading a short passage and looking at examples. They then respond to five questions related to the text.

Help young mathematicians shape their understanding of geometry with this series of worksheets and activities. Starting with an introduction to line segments, lines, and rays, the first unit in this math series continues on to explore...

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....

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...

Some of the most important vocabulary in the study of geometry is presented here. In this PowerPoint, learners view the definitions for points, lines, segments, and rays. The definitions and graphics are clear, and kids are also coached...
