This tool allows you to see a face with perfect symmetry. You can upload photos and it creates a symmetrical image. A great activity to do with students, and great for a bulletin board display.

In this video segment [3:25] from Cyberchase, a plant expert shows Bianca the patterns and symmetry found in nature.

This activity has instructions for making symmetrical portraits of the human face using a digital photograph. It's an activity students of all ages would enjoy.

[Free Registration/Login may be required to access all resource tools.] Graph and compare graphs of quadratic functions in the coordinate plane.

A survey of math graphing techniques includes horizontal and vertical shifts, stretching, lines of symmetry, even and odd functions, and absolute value functions.

This web lesson teaches students about symmetry in two-dimensional shapes.

Try to find the line of symmetry of these 8 figures. If you find it the two figures should coincide.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students about reflections and how to find the coordinates of a reflected figure.

This resource provides an examination of parabolas, both vertical and horizontal, and parabolic functions. It includes six examples and a chart showing how changes in the equation coincide with changes in the graph.

In triangles ABC and ABD, we are given that angle BAC is congruent to angle BAD and angle ABC is congruent to angle ABD. Show that the reflection of the plane about line AB maps triangle ABD to triangle ABC. Aligns with G-CO.B.8.

In this lesson plan on reflections using coordinates, 8th graders explore reflections of line segments using the coordinate plane.

[Free Registration/Login may be required to access all resource tools.] Identify different types of transformations.

This task challenges a student to demonstrate understanding of the concept of measurement.

This MathWorld tutorial provides detailed overviews of the concepts and theorems associated with geometry. Most of the Math World sites are extensive and some require higher math knowledge to understand, links to terms and topics are...

Dr. Math, in a reply to a student question, shows how to derive the equation of a parabola for situations when the line of symmetry is not || to one of the axes.

In this activity, students will identify and record ordered pairs from a coordinate plane. They will examine symmetry about the axes, reflections, and symmetry in nature. They understand geometric concepts like area and perimeter, and...

The most basic quadratic is y = x2. The general technique for graphing quadratics is the same as for graphing linear equations. The quadratics graph as curvy lines (called "parabolas"), rather than the straight lines generated by linear...

Teachers can download this teaching package that looks at light and symmetry through the use of mirrors. Students will enjoy the nine mirror challenges, along with the hands-on activities described in the lessons. Teachers will...

Practice identifying symmetrical shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

A guide to support parents as they work with their students in angle measure and plane figures.

Review inverse functions with your students using this TI-83 activity. Students will find inverses of given functions, determine whether the inverse is a function, graph both, and check for symmetry through the line y=x. The lesson...
