Question

If ABCD is a parallelogram, list 5 thing you know about the sides and angles in the figure.

Answer 1

See explanation

Step-by-step explanation

In parallelogram, ABCD,

1. The opposite angles are equal

`m \angle \: A= m\angle \: C`

`m \angle \: B= m\angle \: D`

2. The adjacent angles are supplementary.

`m \angle \: B + m\angle \:C = 180 \degree`

etc.

3. The diagonals bisect each other

|AE|=|EC|

|BE|=|ED|

4. The opposite sides are parallel.

`AD\parallel BC`

`AB\parallel DC`

5. The sum of all interior angles is 360°
