The given statement is:
"If a triangle has a right angle, then it is right."

Converse:

To check if the statement and its converse form a biconditional, we first need to find the converse of the statement.

The converse is:
"If a triangle is right, then it has a right angle."

Biconditional:

A biconditional statement is true if both the original statement and its converse are true.

1. Original statement:
   "If a triangle has a right angle, then it is right."
   This statement is true because a triangle with a right angle is, by definition, a right triangle.

2. Converse:
   "If a triangle is right, then it has a right angle."
   This is also true, since a right triangle is defined as a triangle with exactly one right angle.

Since both the statement and its converse are true, we can combine them into a biconditional:
"A triangle has a right angle if and only if it is right."

This biconditional is true.

1. What is a biconditional statement, and how is it formed?
2. Can you form a biconditional statement using other properties of triangles (e.g., equilateral triangles)?
3. What is the difference between a converse and an inverse of a statement?
4. How can a conditional statement be false, and what are examples of this?
5. In what cases does the converse of a statement not hold?

Tip: Always check both the original statement and its converse when forming biconditional statements. Both must be true for the biconditional to hold.
