Alternate interior angles were not "discovered" by a single individual; rather, they are a concept in geometry that has been understood since ancient times. The properties of these angles were discussed by ancient Greek mathematicians, particularly Euclid, in his work "Elements." The formal study and application of angles, including alternate interior angles, became more defined in later mathematical developments.
Yes. Alternate interior and alternate exterior angles are congruent.
Alternate interior angles are equal on a transversal that passes through parallel lines.
Alternate interior angles.
Parallel lines cut by a transversal form congruent alternate interior angles.
Not necessarily.
Yes. "Alternate interior" angles are always interior. Angles that are not interior as well as alternate are never accurately described as "alternate interior" angles.
They are 4 alternate interior angles.
Yes. Alternate interior and alternate exterior angles are congruent.
alternate interior and alternate exterior angles
Alternate interior angles are equal on a transversal that passes through parallel lines.
Both alternate interior and alternate exterior angle pairs lie on opposite sides of the transversal.
Alternate interior angles.
Alternate Interior Angles
Parallel lines cut by a transversal form congruent alternate interior angles.
they are congruent i think
Not necessarily.
they are alternate (which means opposite of) the transversal and they are INTERIOR (inside) the paralell lines
