Yeah same😂 I was looking for easy way to remember trig identities(tan2x etc) but they are giving Pythagoras theorem, not even a 5th grader struggle with it
Just practise 50 questions based on pythagoras theorem you will memorize till your doing the 7th question. Every formula can be leart easily by just solving problems related to it.
Ok it's easy, I'll explain. Let's say there's a triangle with each side being a, b and c. Let's say a is 6 cm, b is 5 cm and c is just blank. We need to find c so to do this, we need to square both 6cm and 5cm. This becomes 36cm and 25cm. Now add these together to get 61. Now we have 61=c^2. It's not over since the formula is a^2+b^2=c^2. Now to remove the squared from "61=c^2", you have to square root both sides. The square root of c^2 is just c, you simply just make it c. Now we have c=7.81
This is wrong. Let's take the 3,4,5 triplets, in the diagram example you're saying that you can square root a^2+b^2. 3^2+4^2=c^2, it turns into 3+4=7, so this makes it 7 not 5.
