1 Two parallel lines intersected by another line   A B Corresponding angles (sehadap) Corresponding angles are congruent  A1 =  B1  A2 =  B2  A3 =  B3  A4 =  B4 2. Alternate interior angles (dalam berseberangan) Alternate intirior angles are congruent  A4 =  B2  A3 =  B1 Created by ﺟﻴﻄ ‘12

2   A B Alternate exterior angles (luar berseberangan) Alternate exterior angles are congruent  A1 =  B3  A2 =  B4 4. Same-side/consecutive interior angles (dalam sepihak) Same-side interior angles are supplementary  A4 +  B1 =  A3 +  B2 = Created by ﺟﻴﻄ ‘12

3   A B Same-side/consecutive exterior angles (luar sepihak) Same-side exterior angles are supplementary  A1 +  B4 =  A2 +  B3 = Created by ﺟﻴﻄ ‘12
