When the diameters and/or radii are equal
What is the circles are equal?
A circle can never cut another circle any more than this many times
What is two times (twice)?
The opposite angles of quadrilaterals are
What is equal to two rights?
Exchanging the subject and predicate of a simple statement while retaining its quality and truth.
What is conversion?
A figure contained by a straight line and a circumference of a circle
What is a segment?
If a straight line not through the center is bisected by a straight line through the center then the straight line not through the center is also this
What is bisected?
In a circle the angle at the center is always this compared to the angle at the circumference. At least when the two share similar circumferences as base that is.
What is double?
The universal negative converts in this way
What is universally?
This is the angle OF a segment
What is the angle contained by a straight line and the circumference of a circle?
Lines in a circle further away from this line are progressively smaller
What is the diameter?
In a circle the angle in a segment smaller than a semi-circle is always this
What is obtuse?
Convert the following: All men are animals
What is some animals are men?
The figure which, when an angle is constructed at the center, is bound by the two straight lines forming the angle and the circumference.
What is a sector of a circle?
The tangent line to a circle is always this to the diameter drawn from the point of contact
What is perpendicular (or at right angles)?
From a point outside the circle the lines are greater as as they move towards the diameter on this side of the circle.
What is the concave side?
Complex expression in which, certain things being given, something else necessarily follows because of these.
What is a syllogism?
This when segments of a circle are similar
What is when they admit of equal angles?
Angles in the alternate segment are always this to the angle made at the point of contact and this prop proves it
What is equal to and III 32?
The centers of circles that touch one another are always in this and that always passes through this
What is in a straight line and through the point of contact?
The particular negation has this rule of conversion
What is it does not convert?
