The trigonometry project unfolded in the gentle rhythm of afternoons that blurred into one another.
After that first planning session in the music room, Jade and Rose fell into an easy pattern: they met most days after the last bell, sometimes in the music room when it was free, sometimes on the quiet bench near the courtyard flagpole when the weather allowed measurements.
There was no need to announce it or mark calendars; it simply happened.
One day flowed into the next, the project giving shape to time they already wanted to spend together.
The clinometer came together quickly.
Jade built the prototype at home one evening—protractor taped to cardboard, straw sighted along the top, string with a small washer for the plumb line—and brought it to school the next afternoon.
They tested it first on the flagpole in the courtyard, standing at different distances while one held the device steady and the other recorded the angle and baseline measurement.
Rose knelt to mark the ground with chalk so they could return to the same spots later; Jade noted the numbers in her notebook, her handwriting a little neater when Rose was watching.
They laughed when the first few readings were wildly inconsistent—Jade had tilted the clinometer too much, Rose had forgotten to account for her own height—and adjusted without frustration.
"Next time we use a tripod," Rose said, brushing chalk dust from her palms.
Jade nodded.
"Or at least a friend to hold it level."
They took photos: the clinometer in use, the flagpole against the sky, their shoes next to the chalk marks.
In one shot Jade caught Rose looking sideways at the device with quiet concentration, glasses slipping slightly down her nose.
Jade kept that photo on her phone longer than necessary, telling herself it was only for the poster reference.
Some afternoons they stayed indoors.
They spread graph paper across the music-room table, plotting angles against distances, watching the calculated heights converge toward a stable value.
Rose handled the trigonometry with calm precision—tan of the angle, opposite over adjacent, small corrections for the height of the observer's eye.
Jade sketched the layout, added labels, suggested colors for the final poster so it wouldn't look too clinical.
They talked as they worked, the conversation drifting naturally between the project and other things.
Rose mentioned once that Ethan had tried to "help" by measuring the height of their apartment building from the sidewalk and gotten the angle wrong by twenty degrees.
Jade told her about the time her dad had attempted to calculate the height of their backyard tree using shadows and ended up arguing with the neighbor over property lines.
They both laughed—quiet laughs, the kind that felt private.
One afternoon Rose arrived with two paper cups of hot chocolate from the corner café near the bus stop.
"I passed it on the way," she said simply, handing one to Jade.
The warmth seeped through the cardboard into Jade's fingers.
They sipped slowly while the graphs took shape on the table, steam curling between them.
Another day they stayed late because the measurements needed repeating—the sun had shifted too much earlier—and the school grew quiet around them.
They sat on the courtyard steps afterward, waiting for the light to soften so the angles would be clearer.
Rose pulled her knees up and rested her chin on them.
"I used to hate group projects," she said after a while.
"Always felt like I was the one doing everything or the one being carried."
Jade looked at her.
"This doesn't feel like that."
"No," Rose agreed softly.
"It doesn't."
They finished the bulk of the calculations by Thursday.
The poster boards were bought, sections divided, rough drafts taped together.
Friday they met one last time to assemble the final version in the library after school.
Rose glued photos in careful alignment; Jade wrote the conclusion in her clearest handwriting.
When they stepped back to look at the finished board, it felt surprisingly complete—clean lines, clear graphs, a quiet story of measurement and math.
Rose touched the edge of the poster lightly.
"We did this."
"We did," Jade said, feeling a small swell of pride that had little to do with trigonometry.
They carried the board between them to Mr. Sined's classroom drop-off box before leaving.
The hallways were nearly empty.
Outside, the winter sun was low, turning the sky pale gold.
At the gates Rose paused.
"Next week we present.
But… it was nice working on this with you."
Jade met her eyes.
"Yeah.
It was."
They parted with a small wave, Rose heading toward the bus, Jade toward the walk home.
The project was almost over.
One presentation left.
But the rhythm they had found—the afternoons, the shared tasks, the easy silences—did not feel like something that would end with a grade.
Jade walked home slowly, notebook in her bag, a new line already forming in her mind:
We measured heights together, but the distance between us keeps getting smaller.
She did not write it down yet.
She let it rest inside her, quiet and growing, like the lengthening shadows on the sidewalk ahead.
