Question

Can a quadrilateral ABCD be a parallelogram, If 1) AB=DC=5cm, AD = 3.8 and BC = 3.6 cm and 2) angel A=95° , angle B= 75° 3) angle B = 105° , angle D = 75°​

Answer 1

Answer:

no

Step-by-step explanation:

1. opposite sides of parallelogram are equal bt here bc and ad are not equal

2.angle A and angle B are adjacent angles and sum of adjacent angles of parallelogram is 180 bt here 75+95 is not equal to 180

3. angle B and angle D are opposite angles and opposite angles of parallelogram are equal bt here B is not equal to D

hope it was helpful

Answer 2

Answer

(1) some sum of all angles of a parallelogram is 360 but on adding a + b + c + d = 350

(2) parallelogram formula b×h= 360

(3) There also must be AD=BC parallel because the opposite sides of the parallelogram is equal to each other
