One day, a little girl named Lily went to the park. She saw a big triangle on the ground. It was made of sticks. Lily wanted to play with the triangle, so she tried to pick it up. But it was too heavy! She felt helpless.
Then, a friendly dog named Max came to the park. He saw Lily and asked, "Why are you sad?" Lily said, "I can't pick up this triangle. It's too heavy." Max wanted to help Lily, so he had an idea. He told her to lean on the triangle and push it.
Lily leaned on the triangle and pushed with all her might. To her surprise, the triangle started to roll! It rolled and rolled until it stopped at the other side of the park. Lily and Max laughed and played with the rolling triangle. They never knew that triangles could be so much fun!
