Parallel Lines
Parallel lines never meet and point in the same direction, so they have equal gradients: . In coordinate geometry, showing two lines are parallel usually means proving their gradients are the same.
They keep a constant perpendicular distance apart everywhere.

Where it appears in Add Math
You meet Parallel Lines in the Coordinate Geometry chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.
Our teachers make sure a student can not only recite what Parallel Lines means but use it fluently in a full solution.
The term in three languages
Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Parallel Lines (EN) · Garis Selari (BM) · 平行线 (中文)
