Similar and Congruent Triangles

After reviewing characteristics of seven types of triangles, young geometers discover how to find the missing angle of a triangle. Then, they practice identifying triangles, find missing angles, and find missing side lengths of similar...

A theoretical NASA project is the foundation of this worksheet, in which learners will word to determine congruent and similar figures. They solve 4 word problems where they measure, draw and identify congruent and similar figures from...

Students study triangles. In this triangle lesson plan, students compare and classify triangles while milling to music. Students will also trade triangles so they can match up with other similar triangles. Triangles are provided.

There is more to congruency than just looking similar. Learn the difference and calculate the matching angles and sides to prove the congruence between figures. Lesson has step-by-step slides and follows with an assessment. 

With a hands on technique, learners identify congruent shapes during this activity. Both in groups, and individually, they discuss whether the shapes used in the examples are congruent. Then they head to the computers and go to a website...

Play with polygons and explore the concept of congruence. Interested minds discuss how two objects are similar and different then define congruent and similar figures. This lesson employs the use of three different centers. They use...

Students use interactive geoboards to identify simple geometric shapes. In this making triangles lesson, students describe the properties associated with geometric shapes. Students develop spatial sense and the mathematical meaning of a...

In this congruency activity, students complete problems dealing with congruent and non-congruent figures. Students complete 5 short answer and multiple choice problems.

Second graders are introduced to congruent figures. Using shapes, they classify them into ones that are congruent and non-congruent. They use the internet to identify and match congruent shapes for more practice.

Second graders explore a bag of mixed pattern blocks. As a class they discuss different attributes of these shapes. In this math lesson, 2nd graders search to find shapes that are similar by placing shapes on top of one another to...
