FrostTree187 [#10]a^2 + b^2 = c^2
a=height
b=base
c=hypotenuse
a,c,b are sides of right angle triangle
De-addy [#11]a=height
b=base
c=hypotenuse
a,c,b are sides of right angle triangle
(a+b)² = a² +2ab+b²
De-addy [#11]a=height
b=base
c=hypotenuse
a,c,b are sides of right angle triangle
Cosine Rule:
a^2 + b^2 - 2ab cos C = c^2
also if you rearrange it you get
cos C = (a^2 + b^2 - c^2)/2ab
Sine Rule
a/sin A = b/sin B = c/sin C
FrostTree187 [#13](a-b)^2 = a^2 - 2ab + b^2
u might wanna check ur formula again lil bro
(a-b)(a+b) = a^2-b^2
