Any value that satisfies the equality.
E.g. 2x + 4x = 10 the value that makes this true is 2
or
x^2 = 2 The values that would make it true are 4 and -4, since the squared of any number is always a positive.
This statement is false as all vertical angles are considered congruent but not all congruent angles are considered vertical angles. Any obtuse or acute angle may be considered congruent. If the angle from point A to B is 110 and the angle between B to C is 110 as well then they are congruent
