Description

Covid19 has spread globally. When the Covid-19 pandemic occurs, schools must be closed or partially opened, which affects teaching and learning. Educational innovations to deal with epidemics such as Covid-19 and other urgent epidemics are very important. Therefore, the three cores of Education 4.0 knowledge applicable to pandemics such as COVID-19 are simple, self-learning and technology-integrated knowledge (SST knowledge).

Simple knowledge is the most important core of Education 4.0, it same as Albert Einstein quotes: everything should be made as simple as possible, but not simpler, If you can't explain it simply you don't understand it well enough, We cannot solve our problems with the same thinking we used when we created them.

Peter Chew Method for Solution of Triangle is a simple method to solve the same problem, compare current methods. The Peter Chew Method for Solution Of Triangle is similar to Theorem Remainder, both avoiding the difficulties of using other methods.

Use Peter Chew's method and Peter Chew's rules in Peter Chew's Triangle Diagram to make the diagram guide students to solve any problem of the topic solution of the triangle is simple with just one rule and only once. Programming Peter Chew's Triangle Diagram as Peter Chew's Triangle Diagram Calculator makes it easier for the calculator to solve any problem with just one rule and only once, which will strengthen technology-integrated education, making teaching and learning more effective and fun.

2nd Edition update some information and add some exercises of triangle problems that can be solved with the Peter Chew Method

and Step-by-step solutions to exercises .
