Question

if the non parallel sides of a Trapezium are equal then prove that it is cyclic​

Answer 1

Answer:

Step-by-step explanation:

non parallel sides are equal

so, it is an isosceles trapezium

angles between non parallel sides are equal.

let the angles be a, b, c, d

a=b

c=d

a+c=180

b+d=180

replacing a and b in both equations

b+c=180

a+d=180

opposite angles sum up to 180

so, it is cyclic quadrilateral
