noun
corresponding angles
In geometry, angles that occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, corresponding angles are equal.
平行線では同位角は等しい。
Corresponding angles are equal when lines are parallel.
同位角の性質を使って角度を求めなさい。
Find the angle using the property of corresponding angles.
Vertically opposite angles formed by two intersecting lines; 同位角 involve a transversal crossing two lines.
Compound of 同位 (same position) and 角 (angle), directly describing the geometric concept.
