Endall • Endall is a button that we used to set commands.
If you finish editing you just need to type the name you set, for example this one is triangle2, then only type triangle 2 then the shape will appeared.
What is variable Length • Variable are data which can change. For example : • It can be used to do many things such as triangle, square etc. • It can also be defined in the length of different shapes. • The length can be changed for example for triangle you just type triangle *** the amount of number you want it to be, for example if triangle 200 will be bigger than triangle 100. You can choose your own size of the shape you want , how big you want or how small you want.
