The slope (m) = (delta y)/(delta x) m= (y2-y1)/(x2-x1) Given two points A(a,b) C(c,d) if A is the starting point (x1,y1) and C is the ending point (x2,y2) then m= (d-b)/(c-a) OR if C is the starting point then, m=(b-d)/(a-c) both will give you the same answer.
the midpoint (apex) Between A and B (Apex)
If you have a function f(x), then the tangent can be found by deriving f, denotedd/dx(f(x)) = f'(x). This will give the slope of f(x) at a certain point (a,b).find f'(a), call this m. Now, use the standard form for a line, y = mx+c, plug in the point (a,b) to solve for c. Finally, the equation for the line tangent to a point (a,b) and f(x) is y= f'(a)x + c
When in a triangle, for angle A, B, C; As the symmetric property of congruence , when ∠A ≌ ∠B then ∠B ≌ ∠A and when ∠A ≌ ∠C then ∠C ≌ ∠A and when ∠C ≌ ∠B then ∠B ≌ ∠C This is the definition of symmetric property of congruence.
