What is a triangle?

How do you know a triangle is a triangle. A shape must satisfy these three theorems in order to be classified as a triangle

Finding the side length of an isosceles triangle

In order to find the side length of an isosceles triangle the following formulas are used:

             a = length of legs

 b = base

  h= height

Remember an isosceles triangle has two congruent angles and two congruent sides.

The video works a sample problem in which the side length of an isosceles triangle is calculated using the above formulas.

Area of a triangle GIF

Quick GIF that covers how to find the area of a triangle if you are given the height. If the height is not given there are several methods for finding the height including Herons formula. This page reviews several methods for finding the area of a triangle based on information you are given. Area of triangle

I understand my GIF is not polished and slick. As a teacher I can't spend hours making the perfect GIF but I enjoy creating these simple little Math GIFs with a very basic program, I feel I get a descent product for the amount of time spent creating it. 

Five videos that help with SOHCAHTOA

SOHCAHTOA has been used for years in Geometry classes to help remember the trig functions. Here are five videos that do a nice job of explaining the basic trig functions.

This a very basic video but is very creative and well done.
