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...

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

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 lesson. 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...

In this congruency worksheet, learners 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.

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...

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

Second graders examine two-dimensional shapes using their characteristics. In this shapes lesson, 2nd graders identify similarities and differences by using cut out shapes, diagrams, mirrors, and graphic organizers.
