Presentation transcript:

Grades 4 and 5, Mathematics

 We will learn how to identify, describe, and compare triangles: isosceles, right, equilateral, scalene, obtuse, and acute.  We will discover a rule that states whether or not it is possible to construct triangles from given lengths.

 Access this link to learn about triangles and its classifications.this link

 A triangle is a closed figure made from three line segments  Triangles can be classified based on their angles Acute Right Obtuse

 Triangles can also be classified based on their sides Equilateral Isosceles Scalene

 Use the handouts given to you.handouts

 Use Math Is Fun to create different triangles.Math Is Fun

 Can any three lengths be the sides of a triangle?

 Answer the questions from review review
