2
Sifat-sifat sudut yang berkaitan dengan Rentasan Lintang dan Garisan Selari
Mengenal pasti rentasan lintang, sudut sepadan, sudut selang-seli dan sudut pedalaman.
3
Transversal
Rentasan lintang (transversal) ialah satu garis lurus yang bersilang dengan dua atau lebih garisan lurus yang lain.
4
PQ transversal
Sudut sepadan (corresponding angles):
a dan b, e dan f
c dan d, g dan h
Sudut selang-seli (alternate angles):
b dan g, e dan d
Sudut pedalaman (interior angles):
b dan e, d dan g
5
Apabila rentasan lintang bersilang dengan dua garisan selari,
Sudut sepadan adalah sama.
Sudut selang-seli adalah sama.
Sudut pedalaman adalah tambahan: jumlah (hasil tambah) sudut pedalaman adalah 180° .
6
Contoh 1
Sudut sepadan.
a = b, e = f
c = d, g = h
7
Contoh 2
Sudut selang-seli.
a = b
c = d
8
Contoh 3
Sudut pedalaman.
a + b = 180°
c + d = 180°
