Question

draw an isosceles trapezium and measure its sides and angle​

Answer 1

Step-by-step explanation:

first you have you this is a trapzieum so then you have to proof it as parallelogram and then ,we know that a diagonal divide it into two congruent triangles and we know that co - interior angles is supplementary .angle a +angle d=180 this we call as 1 eq.and angle b+angle c = 180 2 eqn and then adding this 1 and 2 and then you a+b+c+d=360° and we know the sum of angles in quadrilateral is 360 degrees.and isosceles mean two sides are equal and a quadrilateral is a trapzuim when one pair of opposite are parallel.

Answer 2

Answer:

this is a right answer

Step-by-step explanation:

and if AB=DC it will be an isosceles trapezium
