Intersecting Segments Part 2: Outside the Circle
BC is a secant. EC is a tangent. BC and EC intersect outside of circle A. Can you figure out the relationship that exists here?
Try using the lengths of the part of BC outside the circle and the whole length of BC, along with the part of EC outside of the circle and the whole length of EC.
What operations can be used with these values to make a true equation? Also, take note that the values in the image are rounded to the tenths place, so any calculations you make will be approximate.
Hint: For a tangent, the part outside the circle and the whole length will have the same value.
Did you figure out the relationship that exists? Here's a hint:
Outside x Whole = Outside x Whole
(1st secant or tangent) (2nd secant or tangent)
