+11912 Hi everyone,
Today i had a Maths test of 3o marks in school today and i found it hard for me as im not that good in Quadrilaterals!so out here ive got a question for you all to answer and explain me so nicely for i want to know whats its answer as i got this one in the test!so heres it!
Find all the angles of a parallelogram one of whose angles is 55°.
so that was the question and you also along with writing the angles you also have to give the reasons for them like one reason is "in a parallelogram opposite angles are equal"!
so please explain me this nicely becoz u know why!

Opposite angles in a parallelogram are equal so the opposite angle is 55 degrees
Now the angle sum of any quadrilateral (4sides) is 360 degrees so
55+55+x+x = 360 (the four angles add up to 360degrees and opposite angles are equal)
110+2x=360
2x=250
x=125
so the angles are 125, 125, 55, and 55 degrees.
