Answer 1

Jawaban:

A1 = A3 = B1 = B3 = 80°

A2 = A4 = B2 = B4 = 180° - 80° = 100°

Penjelasan dengan langkah-langkah:

A1 = A3 = B1 = B3 = 80°

sudut yg saling berseberangan sudutnya sama

1 garis lurus = 180°

A2 = A4 = B2 = B4 = 180° - 80° = 100°

Answer 2

Jawaban:

A1 = 80°

A2 = 180 - 80

= 100°

A3 = 180 - 100

= 80°

A4 = 180 - 80

= 100°

B1 = 80°

B2 = 100°

B3 = 80°

B4 = 100°

Penjelasan dengan langkah-langkah:

Besar sudut A1 = A3 = B1 = B3

Besar sudut A2 = A4 = B2 = B4

Sudut-sudut tersebut memiliki besar yg sama karena terdapat 2 garis yg sejajar

SEMOGA MEMBANTU ^-^
