"In my day," the ghost sighed, looking at Misha’s phone with mild disappointment, "we didn't have a magical glowing rectangle to tell us the properties of a bisector." Misha froze. "Are you... Boris Ziv?"

"The plane passes through the edge of the base of a regular triangular prism..." he whispered, his voice trailing off into a yawn. He reached for his phone, the familiar urge to look up the bubbling up.

The ghost tapped the paper with his chalk. "Start with what you know. Look at the properties of the parallel lines. Geometry isn't about numbers; it's about logic and beauty. It’s like a puzzle where all the pieces are already there, you just have to choose to see them." "In my day," the ghost sighed, looking at

For the next hour, Misha didn't look at his phone. With the ghost’s subtle hints—a gesture toward an angle here, a whisper about a theorem there—the cross-section of the prism began to take shape. The logic flowed. The "given" led to the "prove," and finally, Misha wrote the most satisfying letters in the Russian language: ( Which was to be demonstrated ).

Misha was currently in the "blankly staring" phase. He was stuck on a problem from the "Stereometry" section for 10th grade. He reached for his phone, the familiar urge

"I am the spirit of the 7th-11th grade curriculum," the figure replied. "And I see you are looking for the easy way out. The GDZ is a map, boy, but it won't teach you how to walk. If you just copy the answer, how will you ever learn to see the hidden lines in the world?"

When he looked up to thank his visitor, the ghost was gone. The book lay flat, looking like any other textbook again. Misha closed the "Ziv" collection with a sense of triumph he hadn't felt in weeks. Look at the properties of the parallel lines
