If the given statement is ‘’If p then q’’, the contrapositive is ‘’If not q then not p’â¶Ä™.

If the given statement is ‘’If p then q’’, the converse is ‘’If q then p’â¶Ä™.

If the given statement is ‘’If p then q’’, the inverse is ‘’If not p then not q’â¶Ä™.

The given statement is If $∠1$and $∠2$are the vertical angles, then$m∠1=m∠2$

and this is true.

Since vertical angles are always equal.

Therefore, the given statement: If $∠1$and $∠2$are vertical angles, then $m∠1=m∠2$is true.

The contrapositive of the given statement is If $m∠1≠m∠2$then $∠1$and $∠2$are not vertically opposite angles.

Thus, it is also true.

The converse of the given statement is if $m∠1=m∠2$, then $∠1$, and $∠2$are vertical angles.

Thus, it is false.

The inverse of the given statement is $∠1$and $∠2$are not vertically opposite angles then $m∠1≠m∠2$.

Thus, it is false.
