 Master the Scalene Triangle with these Seven Specific stages.The Scalene Triangle, like the equilateral triangleand the
isosceles triangle is identified by its line lengths.
A Scalene triangle wil ALWAYS have NO sides equal in length. As with this stage of geometry your child should easily be able to distinguish whether two lines are equal in length or not. If they can't, you need to take them back to develop this skill. The seven steps detailed bellow take you from basic identification all the way through to taking a detailed look at the theorems involving the scalene triangle. These steps also include 'pit stops' to complete fun geometry projects and coloring sheets. These are nice 'breathers' on the learning curve, but they are excellent ways of reinforcing the new knowledge in ways that your kid can get a real life, hands on approach to understanding the basic geometry concepts included. Okay, so let's get started ... 
IdentifyHow do we know a triangle is a Scalene Triangle?An scalene trinagle is simply identified by its line lengths. If NO sides are of equal length then the triangle is scalene, and that's it! However it is also necessary for your child to know another important attribute of this triangle. If nosides are equal in length, then no two angles are equal in size either. In a math question, the given information may indicate either side lengths or angle size for a triangle. In either case students have to identify the triangle as scalene.
A scalene triangle, can also be a Right triangle. This is called a Right scalene Triangle.
Calculate Area and PerimeterHow to calculate the Area and Perimeter of an Scalene Triangle? The Area of a this type of triangle is calculated the same way as EVERY triangle. It is always half the length of the base multiplied by the perpendicular height of the triangle, in this case, the perpendicular height is always the length of the vertical side of the triangle.  The perimeter of this shape is a + b + h 
How to construct an Scalene TriangleTo complete this, you will need a ruler, pencil, compass and a blank piece of paper!Constructing a scalene triangle at the elementary level is actually quite simple. Just draw three lines, ensuring none are of the same length, and you have it! Download one trinagle worksheet, or all of them, to offer your student the practice they need to identify these shapes. 
Relationship to 3D ShapesThe 3d Figures a Kindergarten through sixth grade student is most likely to deal with, created by this triangle will either be a Triangular Prism or pyramid.
Geometric Coloring SheetsThe use of coloring sheets allows your child to start experimenting with triangles. A great first step is to encourage your child to color in triangles adjacent to eachoter with the same color, until their shape starts to look like 'something'. Perhaps that something will be a rectangle or a house. By doing this, your child will start to realize the connection between different shapes. You will find some nice free geometric coloring pages to download here.
