Draw A 5 Point Star

Draw A 5 Point Star
Demostrate the use of:

Coordinates

Direction

Pen Color And Size

Hide A Sprite

Start Scratch and delete the cat

Change the stage to show the coordinates background
This will help locate where you want to draw the star. You can change it later.

Create a sprite to draw the star
Create a sprite called "pen". It can be a small dot (or any shape) because it will be hidden when its script runs.

Add this script to setup drawing the star.
The first thing the script does is "hide" the sprite. This means that we only see the lines on the stage and not the sprite.

The second step erases (clears) all of the lines that were previously draw.

Questions:

Why do we do "pen up" before the "go to"?

What does "point in direction" do?

Use the angles and distances shown to draw the star.
Note: The angles can be use to detrmine how far to turn to draw the next line segment.

Use these "blocks" to move and turn.

Can You Draw These Shapes?
