도형 넓이 유도

직사각형·평행사변형·삼각형의 넓이 공식을 스스로 발견하는 초등수학 학습 앱이에요. 슬라이더로 평행사변형의 한쪽 삼각형을 잘라 옮기면 직사각형이 되어 밑변×높이가 보이고, 삼각형은 똑같은 것을 뒤집어 붙이면 평행사변형이 되어 그 절반(밑변×높이÷2)임을 눈으로 확인해요. 밑변·높이·기울기를 바꿔 가며 넓이가 어떻게 정해지는지 익혀요.
About this app
An interactive educational math application designed to help elementary students discover and understand the area formulas for rectangles, parallelograms, and triangles. Users can manipulate dimensions such as base, height, and slant using steppers, while interactive sliders let them animate cutting and rearranging shapes to visually prove each formula. By transforming complex shapes into simpler ones in real-time, the app turns abstract geometry concepts into an intuitive, hands-on learning experience.
Use cases
- Elementary school students looking to intuitively understand geometry formulas through visual play instead of rote memorization
- Math teachers seeking a dynamic visual aid to demonstrate geometric transformations and area derivations in the classroom
- Parents tutoring their children in basic geometry concepts with an interactive and engaging tool
Features
- Interactive grid visualizer displaying unit squares for rectangle area calculations
- Animated sliding feature that cuts and shifts a triangle piece to transform a parallelogram into a rectangle
- Rotation slider that pairs two identical triangles to demonstrate how they form a single parallelogram
- Customizable dimension steppers to adjust width, height, slope, and vertex positions on the fly
- Real-time formula rendering showing step-by-step mathematical calculations based on current shapes
