The different types of triangles are grouped by either their angles, lines or both. For example and equilateral triangle is a triangle whose SIDES are equal.
A right triangle has one angle that is 90 degrees, also known as a right angle.
An Isosceles triangle is a triangle which has two sides equal in length. But you can also have a Right Isosceles triangle. This is a triangle which has two sides equal in length, but also contains a right angle! To learn more about each triangle, simply click on its image bellow.
Once your student has learned to identify the different types of triangles there is much more to be done! They must now understand how to calculate the perimeter or a triangle along with its area. In the right triangle, they must fully understand the theory behing the hypontenuse of a right triangle
which includes, of course, the Pythagorean Theorem. Along with knowing the construction of the triangle, they must also understand differnt methods of constructing the median of a triangle, along with bisecting lines and angles!
And then, when all the information is absorbed, the must develop the strategic skills to solving triangles when mixed with other shapes! The only way to develop this skill is to practice, practice!
