Postulate 3-1 Corresponding Angles Postulate
If a transversal intersects two parallel lines,then corresponding angles are congruent
The corresponding angles postulate states that when two parallel lines are intersected by a transversal line, the angles that are on the same side of the transversal and in corresponding positions are congruent (have equal measures).
In other words, if two parallel lines are intersected by a transversal line, then the angles that are in the same position (i.e., angles that are across from each other, like the top-left and top-right angles or the bottom-left and bottom-right angles, etc.) will have equal measures.
This postulate is useful in solving various problems related to parallel lines and transversals, such as finding missing angle measures or proving that two lines are parallel by showing that their corresponding angles are congruent.
