One poster shows how triangles are classified by two characteristics: sides and angles.
Two posters show the seven different kinds of triangles “at a glance."
Seven posters show each of the triangles in detail, listing their kinds of angles and sides:
• Acute equilateral
• Acute isosceles
• Right isosceles
• Obtuse isosceles
• Acute scalene
• Right scalene
• Obtuse scalene
★ ★ ★ The Activity

The activity includes two pages: a mat and a page of triangles for students to cut out.
Students must determine the kinds of angles and sides each of the seven triangles have. Then, they have to paste triangles under their correct name.
★ ★ ★ The Worksheets

One is a “Who am I? Triangles Edition” worksheet in which students must name the triangle based on a description.
Another is a “Name that triangle” worksheet, in which students must name the triangle based on a picture.
There are two versions of each worksheet: you can decide whether or not the students have a list of triangle names to choose from.
Complete answer keys are included for both worksheets.
