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...

Try five problems on triangles. Levels A and B focus on shapes that can be created from right triangles. Level C touches upon the relationship between the area of a six-pointed star and the area of each triangle of which it is composed....

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other irregular...

You'll never have to search for another worksheet again after downloading this extensive collection of Saxon math materials. With over 600 pages of example problems and skills practice exercises, this is a must-have resource for any...

Students explore a variety of patterns. They examine the patterns in a flower design made of triangles surrounding a square. Pupils complete a table listing the number of triangles needed to complete various flower designs. Students make...

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.

Are congruent shapes compatible? Congruent shapes are identical to one another, and throughout the assessment, young mathematicians identify given shapes as congruent.

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. 

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...

Learners discover three lettered postulates that prove triangles congruent.
