For the given statement, write the converse, inverse, and contrapositive. if a figure is a cube, then it had eight vertices.

First, we recall what the terms converse, inverse, and contrapositive mean.
Conditional statement: If p then q.
Converse: If q then p.
Inverse: If not p then not q.
Contrapositive; If not q then not p.

Conditional statement:
If p then q.
If a figure is a cube, then it has eight vertices.

p = a figure is a cube
q = it has eight vertices

Converse:
If q then p.
If a figure has eight vertices, then it is a cube.

Inverse:
If not p then not q.
If a figure is not a cube, then it does not have eight vertices.

Contrapostive:
If not q then not p.
If a figure does not have eight vertices, then it is not a cube.
