3. 1 Identify Pairs of Lines and Angles
Transversal – a line that intersects two or more coplanar lines at different points. t
Corresponding Angles (C) – have corresponding positions. For example: label 2 and 6 t 2 6
Corresponding Angles (C) What shape do corresponding angles make? t 2 F 6
Alternate Interior Angles (AI) – lie on alternate (opposite) sides of the transversal on the interior (inside/between) the two lines. For example: label 4 and 5 t 4 5
Alternate Interior Angles (AI) What shape do alternate interior angles make? t Z 4 5
Alternate Exterior Angles (AE) – lie on alternate (opposite) sides of the transversal and on the exterior (outside) of the two lines. For example: label 1 and 8 t 1 8
Alternate Exterior Angles (AE) Do alternate exterior angles have a shape? t 1 8 Not really
Same Side Interior Angles (SSI) – lie on the same side of the transversal and on the (inside) of the two lines. For example: label 3 and 5 t 3 5
Same Side Interior Angles (SSI) What shape do Same Side Interior angles make? t 3 5 C
Don’t forget!!! Vertical Angles (V) 1 2 X shape Linear Pair (LP) 3 4 Slanty T shape
