Math Problem Statement
Solution
To determine which angle is congruent to in the provided diagram, let's examine the structure of the angles and lines.
Solution
-
Identify : is the angle formed at point , between line segments and .
-
Check for Vertical Angles: Since the lines intersect at point , vertical angles are formed. Vertical angles are congruent. Therefore, the angle directly opposite would also be congruent to it.
-
Identify the Congruent Angle: The angle opposite across point is .
Thus, the angle congruent to (other than itself) is:
