Starship Radar: Coordinate Geometry

  • Apr 15
  • 1 min read

The Mission:

Calculate the straight-line distance between your starship and the target enemy ship using the Pythagorean theorem on a coordinate plane!


Math Skills:

  • Coordinate Geometry: Finding horizontal (Base) and vertical (Height) distances between two (x, y) points.

  • Pythagorean Theorem: Applying the formula a^2 + b^2 = c^2 to find the hypotenuse.


How to Play:

  1. Look at the (x, y) coordinates of your ship and the target ship on the radar grid.

  2. Click Analyze Radar to automatically draw the right-angled triangle on the map.

  3. Calculate the length of the Base and Height, use the Up/Down arrow buttons to input your answers, and click the Submit (✔) buttons.

  4. Watch the Pythagorean theorem calculation on screen and see the laser destroy the target! Click the Next Target button to play again.

星際雷達定位


任務簡介:

在坐標平面上運用 畢氏定理，計算出你的飛船與敵機目標之間的直線距離！


數學技能:

  • 坐標幾何: 找出兩個 (x, y) 坐標點之間的水平（底邊）和垂直（高）距離。

  • 畢氏定理: 應用公式 a^2 + b^2 = c^2 來求出斜邊長度。


玩法說明:

  1. 查看雷達網格上你的飛船和目標飛船的 (x, y) 坐標。

  2. 點擊 「分析雷達」(Analyze Radar)，系統會在圖上畫出直角三角形。

  3. 計算底邊和高的長度，使用 上下箭頭 按鈕輸入答案，然後點擊 「提交」(✔) 按鈕。

  4. 觀看螢幕上的畢氏定理計算過程，並看著雷射摧毀目標！點擊 「下一個目標」(Next Target) 按鈕再玩一次。
