In this lesson, you'll learn about the three classifications of triangles based on angles and sides: acute, obtuse, and right triangles and scaling, isosceles, and equilateral triangles. You'll also learn how to solve problems using this knowledge, such as finding the length of sides in triangles based on coordinate points and determining whether a triangle is isosceles or equilateral.
Learn all about triangles -- their classifications and properties, and how to solve problems with this knowledge.
