Now for the important definitions!
A secant is an intestect with the circle in two points
The two points subtended to the same arc are equal in measure
A tangent is an intestect with the circle in one point this circle provides an example for the point of tangency
All of this yapping and we still didn't finish?! I will jump from the window!
While the inscribed angle is equal to half it's arc
Now let's get to the lessons with equations and and arcs!
The central angle is equal to it's arc
To get the circumfrence of the circle you have to use the equation C=2πr Radius is half the Diameter which is the line that is shown in this circle
228
If two chords are intersecting each other they are equal to one another!for example: 5*3=6*X
5
The area between two tangent is equal to the difference between two arcs divided by 2Example: 228-132/2=48 which is X
6
X
3
132
x
There is much more but I will give you the last important things and we can continue later, and I will give you a nice example
What is all of this explaining bro, I became an old man
The central angle is equal to it's arc
