Question

can a quadrilateral ABCD be a parallelogram if. angle a + angle c = 180 degree. angle b = 80 degree and angle d = 65 degree. AB = DC = 10 CM , AD = 5 CM, BC = 6. 4 cm​

Answer 1

Answer:

No

Step-by-step explanation:

Sum of internal angles of a parallelogram must be 360 degrees.

if. angle a + angle c = 180 degree. angle b = 80 degree and angle d = 65 degree

Then,

A+ B+C+D =360

180+80+65=360

325 does not equal to 360

Therefore, ABCD isn't a parallelogram.
