Question

your python program has this code.
for n = 1 to 10:
position = position + 10 # move the position 10 steps.
direction = direction + 90 # change the direction by 90 degrees.
you decided to write your program in a block programming language.
what type of block do you need to accomplish what this line does?
direction = direction + 90 # change the direction by 90 degrees.

event
control
voice and graphics
motion

Explanation:

In block - based programming, the direction = direction + 90 line is related to changing the orientation or movement direction of an object. Motion blocks are typically used to handle aspects such as position, direction, and movement of sprites or objects in a programming environment. Event blocks are for things like when a key is pressed or a timer runs out. Control blocks are for loops (like the for loop in the original Python code) and conditionals. Voice and graphics blocks are for audio and visual display - related operations. Since the line is about changing the direction (a movement - related property), the motion block is the most appropriate.

Answer:

motion
