Coordinate Planes and Architecture
::协调规划和建筑Coordinate planes can be a useful tool for architects. Blueprints are usually laid out on a coordinate grid to help identify angles and side lengths.
::坐标机可以成为建筑师的有用工具。 蓝图通常放在坐标网格上,以帮助识别角度和侧长。For this interactive, you will use the distance between points on a coordinate plane to calculate the perimeter of a polygon.
::对于此互动, 您将使用坐标平面上的点数之间的距离来计算多边形的周界 。Discussion Questions

Making a Robot Part 9
::制作机器人第9部分Now that the robot you began programming in the lesson is complete, you can move the robot through a maze. The function moveTo(x,y) has been added to the commands. You can use this command to move a robot straight to a certain location, which may come in handy if you need to move diagonally. Enter the coordinate for and coordinate for of the location where you want to go. If you enter moveTo(5,6), this will move the robot in a straight line to the point (5,6), relative to the original starting location.
::现在课程中开始编程的机器人已经完成, 您可以通过迷宫移动机器人。 函数移动To( x, y) 已被添加到命令中。 您可以使用此命令将机器人直接移动到某个位置, 如果您需要移动对角, 则可以使用此命令。 输入 x 和 Y 坐标的 x 和 y 坐标, 您想要移动的位置 。 如果您输入 To( 5, 6) , 这将将机器人直线移动到点( 5, 6 6 ) , 相对于初始启动位置 。The list of all available commands is below:
::所有可用命令列表如下:-
stepsY
- This command will move the robot n steps forward, or n steps backward. The command stepsY(4) will move the robot 4 steps forward, and the command stepsY(-2) will move the robot 2 steps backward.
::stepsY- 此命令将移动机器人 n 步向前, 或 n 步向后。 命令步骤Y(4) 将移动机器人 4 步向前, 命令步骤Y( 2) 将移动机器人 2 步向后。
-
stepsX
- This command will move the robot n steps right, or n steps left. The command stepsX(4) will move the robot 4 steps right and the command stepsX(-2) will move the robot 2 steps left.
::stepsX- 此命令将移动机器人 n 步向右, 或 n 步向左。 命令 stepsX(4) 将移动机器人 4 步向右, 命令 stepsX(-2) 将移动机器人 2 步向左 。
-
location() - This command returns two values, telling you the current
location and
location of the robot.
:) 位置 - 此命令返回两个值, 告诉您机器人的 x - 位置和 Y - 位置 。
-
reset() - This command will move the robot to the starting position and will set the total number of steps taken to 0.
::重置 () - 此命令将把机器人移动到起始位置, 并将将所采取步骤的总数设置为 0 。 -
total() - This command will return the total number of steps taken by the robot.
::总计 () - 此命令返回机器人所采取步骤的总数 。 -
moveTo(x,y) - This command will move a robot to the
coordinate and
coordinate entered by the user.
::移动To(x,y) - - 此命令将把机器人移动到用户输入的 x - 坐标和 y - 坐标 。
For the following interactive, you will be using everything you know about locations and distances on the coordinate plane to navigate a robot through a maze.
::在接下来的交互式操作中, 你将使用你所知道的 坐标飞机上的位置和距离 来导航机器人穿过迷宫。
Science Connection
::科学连接This Physics Simulation involves a very similar robot motion and location system to the one designed over multiple lessons in this series.
::这种物理模拟涉及一个非常相似的机器人运动和定位系统,与本系列多个课程上设计的系统非常相似。See if you can identify the similarities and determine how the robot's programming might work.
::看看能不能找出相似之处 确定机器人的程序如何运作Summary -
