Ответ:

Объяснение:

Поскольку диагональ и сторона трапеции параллельны плоскости альфа, то эти две линии лежат в одной плоскости. Следовательно, плоскость, которой лежит трапеция, параллельна плоскости альфа.

Таким образом, плоскость альфа и плоскость, которой лежит трапеция, либо параллельны друг другу, либо совпадают.

On behalf of our entire family, I would like to extend our most sincere thanks and appreciation to you Steve and the rest of your terrific staff for making our short stay with you one of the most incredible times of our lives. We find it hard to express the excitement, euphoria, and sheer enjoyment we have experienced while on safari, the memories we have of what we have seen and heard will stay in our minds forever.
Our accommodations were wonderful and perfect for our African adventure; our dining experiences were delightful; and the service we received was perfect and as warm and friendly as we have ever experienced anywhere in the world. However, the highlight of our stay took place in the bush.

We found it hard to believe that we were able to see everything we did in just a few short days, and you made it all possible. Please be sure to tell your staff how wonderful they made our times in the bush, and how much we appreciated their incredible efforts on our behalf.
Just to show you how extraordinary our safaris were, I have included a few pictures out of the thousands I took during the three days we stayed with you.
Thanks again for giving us a “once-in-a-lifetime” experience. I hope we will be able to stay in touch, and I can learn when the best time of the year will be for our return visit soon, and perhaps learn more about the exciting things that are happening at Sabi Sabi.
