- AreEqual( <Object>, <Object> )
- Decides if the objects are equal.
Normally this command computes the result numerically. This behavior can be changed by using the Prove command.
- Example:
AreEqual(Circle((0, 0),1),x^2+y^2=1)
yields true since the two circles have the same center and radius.
Notes:
AreEqual(Segment((1, 2), (3, 4)), Segment((3, 4), (1, 6)))
is different fromSegment((1, 2), (3, 4)) == Segment((3, 4), (1, 6))
as the latter compares just the lengths- See also AreCollinear, AreConcyclic, AreConcurrent, AreCongruent, ArePerpendicular, AreParallel, IsTangent commands.
