Question 85770: A diameter that is perpendicular to a chord___the chord and its arc
Tangents to a circle from a point are (a)___ and (b) each tangent is ___ to the radius drawn to the point of tangency

A diameter that is perpendicular to a chord___the chord and its arc
Let's draw a circle:

Now let's draw a chord:

Now let's draw a diameter perpendicular to that chord

As you can see from the figure, that diameter bisects both the chord and its
arc. The word is "bisects".

Tangents to a circle from a point are (a)___ and (b) each tangent is ___ to the radius drawn to the point of tangency
Draw a circle:

Draw two tangents from an arbitrary point outside the circle:

They sure do look equal in lengthe, so the word you want for (a) is "equal"
Draw in an upper radius to the upper point of tangency:

It certainly looks like that upper radius is perpendicular to the upper tangent.
Draw in a lower radius to the lower point of tangency:

It certainly looks like that lower radius is perpendicular to the lower
tangent.
So the word for (b) is "perpendicular".
