The Angle block displays an interactive angle visualization. Use it to demonstrate angle concepts, show specific angle measurements, or illustrate different angle types. This is a display block for teaching and demonstration. learners can view and interact with the angle but aren’t assessed on it.
For assessable angle activities where learners identify or measure angles, use the Angle Question block instead.

​
When to use Angle blocks

Angle blocks work well for:
  • Demonstrating angle types (acute, right, obtuse, straight, reflex)
  • Showing specific angle measurements as visual examples
  • Illustrating geometry concepts in explanations
  • Providing reference angles alongside question content

​
Settings

​
Display settings

​
Degrees
slider
default:"90"
The initial angle measurement in degrees (0–360).
​
Show degrees
switch
default:"true"
When enabled, displays the numeric degree value on the angle.
​
Show angle name
switch
default:"true"
When enabled, displays the angle type name (acute, right, obtuse, straight, reflex).
​
Show circumference
switch
default:"true"
When enabled, displays the arc showing the angle measurement.
​
Random rotation
switch
default:"false"
When enabled, the angle is randomly rotated each time it’s displayed. Useful for showing that angle size doesn’t depend on orientation.

Tips for teachers and parents

Best practices:
  • Use alongside explanatory text to reinforce angle concepts
  • Enable Random rotation to show learners that angles look the same regardless of orientation
  • Hide the degree value when you want learners to estimate or identify the angle type first
  • Pair with Angle Question blocks to create teach-then-assess sequences
  • Use multiple Angle blocks to compare different angle sizes side by side
  • Angle Question. Assessable version where learners identify or measure angles
