True : State whether the following statement is true or false:If two lines intersect, the do so at one point.

True : State whether the following statement is true or false:Through any three non-collinear points exists one plane.

Addition Property of Equality : If a=b, then a+c = b+c

Subtraction Property of Equality : If a=b, then a-c = b-c

Transitive Property of Equality : If a=b and b=c, then a=c

Substitution Property of Equality : If a=b, then a can be substituted for b in any equation or expression.

Vertical Angles Theorem : Vertical angles are congruent.
