Here I am completing an example of finding the distance from a point to a line. I also explain whet the distance is. In the next Video, I cover how to use technology, GeoGebra, to check our answer.

In the prior video I found the distance from a point to a line without fancy technology. In this Video, we check our work using GeoGebra. geogebra.org

Here I am finding lines through a give point that are either parallel or perpendicular to a given line. We use https://www.geogebra.org/calculator at the end to check our work.

Direct Instruction Geometry Section 3.5, Ratios of Directed Line Segments. An Example is worked out by hand and then we check the work with Technology. We use this applet in particular: https://www.geogebra.org/m/dyh3ejt2

https://www.geogebra.org/m/hdpusucp Sampling Distribution of difference of proportions Calculator. This calculator will Check conditions for normality and will compute the Mean and Standard Deviation. I use this wonderful calculator, which I created, to solve a simple Statistics problem.

https://www.geogebra.org/m/szzkzjc7 The tool found above will Check if a distribution of sample proportions will be approximately normal. It will also state the mean of such a distribution and the standard deviation.
