Hi! Today we began talking about the wonderful world of triangles. We classify triangles in two ways: by its side lengths and by its angle measures.
Know the definitions of scalene, isosceles, equilateral, acute, obtuse, right, and equiangular triangles!
Know how to label or identify the parts of isosceles and right triangles.
Know how to use the distance formula to find the length of the sides of a triangle on a coordinate plane. Use the lengths to determine what kind of triangle it is.
