Expert verified

The equation that relates AD and BE is BE=2AD.

Step by step solution

01

Step 1. Highlight Triangle ABE in the given figure.

02

Step 2. Description of step.

Consider 螖TBE. From the figure, it can be observed that TA=ABandTD=DE.

03

Step 3. Description of step.

From the figure, it can be observed that AD is the midsegment of 螖TBE. The midsegment theorem states that the length of the midsegment is half of the base of the triangle. Therefore,

AD=BE2BE=2AD

Therefore, an equation that relates AD and BE is BE=2AD.
