The Eiffel Tower is located in Paris, France. It was constructed between 1887 and 1889 to be the entranceway to the 1889 World's Fair and to celebrate the 100th anniversary of the French Revolution. The Tower was opened to visitors on May 6, 1889.
Gustave Eiffel's design was chosen from among 107 that were submitted to the World's Fair design competition. However, many Parisians, especially artists, did not like his design and protested the tower's construction. They thought it would be an eyesore, but once it was built, most Parisians soon loved the tower.
The tower is made of iron and weights over 10,000 tons. It is 324 metres tall, including antenna at its top, and has a staircase with 1,665 steps. There are also elevators to take visitors to the top platform where there is a panoramic view of Paris. The original elevators, now computerised, are still in use. Over 60 tons of paint are applied to the tower every seven years to keep it from rusting.
The Eiffel Tower has become a symbol of Paris. It is the most recognised monument in Europe, and many people think it is an architectural masterpiece. Over 250 million people have visited it since May of 1889.

a.
TH1: A nằm giữa O và B
Khi đó, do AB = 3cm, OB = 6cm nên A là trung điểm OB
=> OA = AB = 3 (cm)
TH2: A nằm ngoài OB
Khi đó, ta có OB + BA = OA
=> OA = 3 + 6 = 9 (cm)
b.
TH1: A nằm giữa O và B
Khi đó, CA = OC + OA = 3 + 3 = 6 (cm)
TH2: A nằm ngoài O và B
Khi đó, CA = OC + OA = 9 + 3 = 12 (cm)

Dear [Friend's Name],
I hope this email finds you well and in good spirits. It has been a while since we caught up, and I have some exciting news to share with you! Recently, I had the opportunity to explore the breathtaking landscapes and vibrant culture of Vietnam, and I couldn't help but think about what an amazing experience it would be to share it with you.
Vietnam is a country that captivates the senses with its rich history, stunning natural scenery, and warm hospitality. From the bustling streets of Hanoi to the serene beauty of Ha Long Bay, there's something for everyone. The vibrant colors of the lantern-lit streets in Hoi An and the bustling markets of Saigon create an atmosphere that is both lively and enchanting.
One highlight of my trip was exploring the ancient temples and pagodas, each with its own unique story and architectural charm. The delicious street food, from savory pho to fresh spring rolls, is a culinary adventure you won't want to miss. And let's not forget the warm and friendly locals who made every step of the journey memorable.
I've attached a few photos to give you a glimpse of the incredible landscapes and cultural experiences I encountered. However, no photo can truly capture the magic of being there in person.
Considering your love for [specific interests], I believe you would thoroughly enjoy and appreciate the beauty that Vietnam has to offer. If you're up for an unforgettable adventure, I'd love to plan a trip together or provide more details on the must-visit places.
Let me know your thoughts, and perhaps we can start planning a Vietnamese adventure soon. I'm eager to hear from you and share more about this incredible journey!
Wishing you all the best,
