Question

Parallelogram Properties - Diagonals
delta math

Answer 1

DE=18

Explanation:

The reason is because that parallelogram ABCD has most of the sides equal to each other.

The length of DB = 36 and half of 36/2 gets us DE.

DE=36/2=18

DE=18 also equals to BE=18

Answer 2

Diagonals of a parallelogram bisect each other

So

• DE+BE=DB

Putting DE=BE

• 2DE=DB
• DE=DB/2
• DE=36/2
• DE=18
