Within the TI-Nspire Shapes menu, you find the Circle, Triangle, Rectangle, Polygon, and Regular Polygon tools. Here are the steps to use the Circle tool: [more…]

### Dynamically Explore Constructions on the TI-Nspire

One of TI-Nspire’s most powerful features is its ability to grab and move objects, enabling you to observe changes happening dynamically in real time. This is especially true of constructions, including [more…]

### Perform Calculations and Using the TI-Nspire Attach Feature

Calculations can be used to make sense of the measurements that were taken. The TI-Nspire Attach feature is a handy way to display the results of the calculations and measurements. You can use these tools [more…]

### Measure Length and Customize Scale on the TI-Nspire

With TI-Nspire's Length Measurement tool, you can measure the perimeter of a polygon, the circumference of a circle, the length of a segment, or the distance between any two points. For this example, you [more…]

### Use the Rotation Tool on the TI-Nspire Transformation Menu

The TI-Nspire Transformation menu provides five different transformations: Symmetry, Reflection, Translation, Rotation, and Dilation. The Rotation tool is a good choice for creating a triangle with specific [more…]

### How to Label Objects on the TI-Nspire

The TI-Nspire allows you to add labels to any object. Use these steps to label the vertices of an equilateral triangle, A, B, and C: [more…]

### How to Move and Resize Objects on the TI-Nspire

You can move or resize any object on the TI-Nspire. However, you face some constraints based on the type of drawing you have constructed. For example, consider an equilateral triangle. This object can [more…]

### How to Select Multiple Objects on the TI-Nspire

You may want to select multiple objects within the TI-Nspire Geometry application for two reasons. First, multiple selected objects can be translated. Second, all selected objects can be deleted by pressing [more…]

### How to Change an Object's Attributes on the TI-Nspire

Besides changing the attributes of a graph, you can also change the attributes of a geometry object on the IT-Nspire. Press **[MENU]**→Actions→Attributes to invoke the Attributes command. Then, move to the [more…]

### Use the TI-Nspire Lock and Pin Features

The TI-Nspire Geometry application offers Lock and Pin features. If a point is pinned, it can’t be moved unless it is unpinned. Other geometric objects and text can also be pinned, which is a nice feature [more…]
