1, Pleasant Goat and Boiling Goat see a mirror hanging on the tree. In the mirror, the wolf points to a clock. The time on the clock is 10: 50. Cang Lang said, "Do you know the real time? If you don't know how to do it, you are an idiot. If you know how to do it, you sheep are still idiots! " Boiling sheep thought for a long time and said, "Isn't the time seen in the mirror 10: 50?" Pleasant Goat said, "The object seen in the mirror is opposite to the actual object."

2. The boiling sheep said, "Could it be 2: 20?" Pleasant Goat said, "No, the actual time and the time in the mirror add up to 12." Boiling sheep also began to understand, saying, "I see, the actual time is 1: 00 10."

Pleasant Goat and Boiling Goat walked for one kilometer and went downhill. They saw three equilateral triangles drawn on another piece of paper without crossing. How many angles are there and how many right angles are there? Then the boiling sheep said, "It's not easy." Pleasant Goat said, "Every triangle has three angles, and three triangles make up 339, with nine angles. An equilateral triangle has no right angle. "
