Question

an isoscales trapezoid has base angle of 120 degree what is the measure in each of the Other angle of the trapezoid​

Answer 1

Answer:

120°, 60°,60°

Step-by-step explanation:

As given trapezium is isosceles so adjacent angles along with parallel side are equal to each other , So

∠ BAD = ∠ ABC = 120°

We know adjacent angles ( Along with non parallel sides ) are supplementary in trapezium , So

∠ BAD + ∠ CDA = 180° , Substitute value from given diagram we get :

120° + ∠ CDA = 180° ,

∠ CDA = 60°

And

∠ ABC + ∠ DCB = 180° , Substitute value from given diagram we get :

120° + ∠ DCB = 180° ,

∠ DCB = 60°

Therefore,

Other angles of given trapezium = 120° , 60° and 60° ( Ans )

Answer 2

Answer:

60degree and 60 degree and 120 degree
