Abstract—The objective of Peter Chew Triangle Diagram is to give complete image of topic solution of triangle. Peter Chew Triangle Diagram will suggest a single rule that allows us to solve any problem of triangle simple, directly and more directly. There are two important rules for the topic solution of triangle, vice like the sine rule and the cosine rule. The sine rule generally is used to find a non-included angle when we’re given two sides and a non-included angle or the opposite side angle given when are given two angles and one side. The cosine rule generally is used to find the angle when we’re given three sides or to find the third side when are given two sides and the included angle. Peter Chew Method can let us to find the third side simple when given two sides and a non-included angle. Peter Chew Rule allow us to find a non included angle simple, directly when given 2 sides and an included angle. Apply Peter Chew Triangle Diagram to Education 4.0 Calculator allows the Calculator to solve any problems in topic solution of triangle simple, directly and more accurate. This can be effective in let student interest in using technology while learning mathematics especially when analogous COVID-19 issues arise in the future. In addition to applying Peter Chew Triangle Diagram in the Education 4.0 calculator, Peter Chew Triangle Diagram are also applicable to many different Engineering fields, Pool Game and Criminology.

Keywords—Peter Chew triangle diagram, solution of triangle, Education 4.0 calculator, Peter Chew
