1.	In figure ABCD is a Trapezium in which AB\|\|DC .
Answer» ANSWER: AB and cd are parallel line and ad be its transversal angle a + angle d = 180⁰ ( interior angle test ) 105⁰ + X = 180⁰ x = 180⁰ - 105⁰ x = 75⁰ similarly ab ll cd and BC be its transversal angle B + angle C = 180⁰ ( interior angle test ) 115⁰ + y = 180⁰ y = 180⁰ - 115⁰ y = 65⁰

Answer»

AB and cd are parallel line and ad be its transversal

angle a + angle d = 180⁰ ( interior angle test )

105⁰ + X = 180⁰

x = 180⁰ - 105⁰

x = 75⁰

similarly ab ll cd and BC be its transversal

angle B + angle C = 180⁰ ( interior angle test )

115⁰ + y = 180⁰

y = 180⁰ - 115⁰

y = 65⁰
