Write the following arguments in symbolic form and test their validity. You can use either the definition or the theorem. 1. If two sides of a triangle are equal, then the opposite angles are equal. Two sides of a triangle are not equal. Therefore, the opposite angles are not equal. 2. If 7 is less than 4, then 7 is not a prime number. 7 is not less than 4. Therefore, 7 is a prime number.
