Question

In the parallelogram what angle is supplementary to BCD

Answer 1

I'm going to answer in statement proof form.

Statement | Proof

mANGLE(ABC) is congruent to mANGLE(ADC) Properties of a Parallelograms

3(BCD)+(BCD)=180 Supplementary Property of Parallelograms

4(BCD) = 180 Simplify

BCD=45 Division property of Equality

180-45=ABC Properties of Supplementary Angles

135=ABC Simplify

135=ADC Transitive property of equality

Answer 2

The sum of any two consecutive angles of a parallelogram is equal to the ... The angles BCD and DCF are adjacent supplementary angles and make in sum the
