The intersecting secant-tangent theorem says that
where T is the point at which line segment PO touches the circle. Similarly,
so we have
OP is of course as long as itself, and AO and BO are radii of the same circle so they have the same lengths.
This means triangles APO and BPO are congruent, which means angles APO and BPO are congruent, so angle APB is bisected by PO.
Answer:
True.
Step-by-step explanation:
It is because it is in the form and this equals
.
Why it is in that form: well comparing , we have
. Testing, plug in those values:
.
This has the squared form of .
Test if you like:
Use foil to expand:
First: x(x)=x^2
Outer: x(1)=x
Inner: 1(x)=x
Last: 1(1)=1
---------------Add together
It does indeed equal.
