Next Goal

Let’s add a line segment

so that we make a nice

angle.


Line segments

Line Segments

  • Tap the .

  • Select line.

  • Tap the canvas.

  • Tap on one point from your original line. Create your second point somewhere off the line.

  • You should have a line and a line segment connected at a single point.


Measure an angle

Measure an Angle

  • An angle is defined by three points. The first endpoint, a vertex, and the second endpoint.

  • Tap the .

  • Select angle.

  • Tap the canvas.

  • Tap on the three points on the screen. MAKE SURE that the second point you select is the point that the line and segment have in common.


Measure a length

Measure a Length

  • Tap the .

  • Select length.

  • Tap the canvas.

  • Tap on the line segment.

  • Move one endpoint of the line segment. Notice how both measurements change.


Construct a midpoint

Construct a Midpoint

  • Tap the .

  • Select midpoint.

  • Tap the canvas.

  • Tap on the line segment.

  • Drag one of the endpoints of the line segment around. Notice how the midpoint moves too.

Result

Your design should look

Similar to this.

(Note: The measurement

Values may differ)


Exploration

Exploration

  • Explore on your own.

  • Try to figure out what and do.

  • Can you draw a right triangle?
