Image Tool including the Protractor and Ruler

Description

The Image Tool feature in Learnosity allows authors to use rulers and protractors as part of a question stimulus, or add their own custom defined images as features.

Students can easily interact with image tools by dragging and rotating them.

Ruler

There is a set of default rulers available in Learnosity featuring rulers of different sizes, with cm or inch measurements.
When the feature is selected the ruler type can be specified in the Image field. For this, enter any of the following ruler types into the text box:

  • ruler-15-cm
  • ruler-30-cm
  • ruler-6-inches
  • ruler-12-inches

The selected ruler will be displayed in the Preview section.

Show rotate icon option allows students to rotate the ruler.

When Button is enabled ruler will only appear when the student clicks on the button. The button image can also be specified. Simply entering "ruler" into the Button Icon field will display a ruler icon. Custom icons can also be used. Click on "..." to upload or embed your image.

Authors can also change the button label by entering text into the Label field.

Protractor

When the Protractor feature is selected the protractor will be simply displayed in the Preview section.

There are several options that can be specified for protractors:

  • Show rotate icon - When enabled it will allow students to rotate the protractor.
  • Button - Protractor will only appear when the student clicks on the button.
  • Button Icon and Label can be changed for protractors the same way as for rulers.
