Question

If ABCD is an isoceles trapezium angle A=40° then find all other angles of trapezium ​

Answer 1

Answer:

angle 1=40, angle 2=40, angle 3=140 ,4=140

explanation:-

angle 1= angle 2(as one pair of side are equal )

angle 3=angle 4(as 180 -40=140( angles on same side of transfel)

Answer 2

Answer:

angle B=40°,c=140°,d=140°

Step-by-step explanation:

abcd is a isoceles tapezium this means that out of angles 2 pair of angles will equal

this means that angle a=angle b

and angle c=angle d

angle a=40°=angle b

angle a+angle b=40+40

80-360=280°

remaining angles are c and d

then 280÷2=140

and 140=angle c

angle c=140=angle d

so angle a=40 and so on
