Did you try Googling those?
no it dont help me
Mmmm.... okay hang on and let me see if I can help :)

Question 1: The shorter leg is 30 degrees so, 3 times the length of the shorter leg put into a quick equation is 30 x 3. So what is 30 x 3?
30 x 3 = 90. So that is why question 1 is 3 times the length of the shorter leg
I'm not sure how to explain question 2. Sorry :(
its ok
do you know pythagoras theorem ?
no
in a right angled triangle, by pythagoras theorem, |dw:1359742322102:dw|
kk
for 45-45-90 triangle, since 2 angles are equal, the two legs will be equal.|dw:1359742414724:dw|
before that, you know what a hypotenuse is ?
no
ratios of a 30 - 60 - 90 right triangle are \[1:\sqrt{3}:2\] for short side : long side : hypotenuse
|dw:1359744962959:dw|
this tell you the longer leg is \(\sqrt{3}\) times the shorter leg
for a 45 - 45 - 90 triangle ratios are \[1:1:\sqrt2\]
in other words, both legs are the same length (since it is an isosceles triangle) and the hypotenuse has length \(\sqrt{2}s\) is \(s\) is the length of the side
thanks
i still dont get it
@chrisshort and @ritez get on webex
