Segment Addition Postulate
The purpose of this handout is to provide students an opportunity to learn the keystrokes involved using the TI-Nspire and to verify the Segment Addition Postulate.https://education.ti.com/en/activity/detail/segment-addition-postulate
Segments and Chords in a Circle
This activity is designed to allow students an opportunity to gain an understanding of the relationship among the segment measures formed by intersecting chords in a circle. It includes an interactive geometry page, some circle problems, and a Euclidean proof.https://education.ti.com/en/activity/detail/segments-and-chords-in-a-circle

The Sprinkler and the Lawn
Students will apply the concepts of angle bisector, incenter of a triangle, and percentages to solve a real-world problem involving a circular sprinkler and a triangular-shaped lawn.https://education.ti.com/en/activity/detail/the-sprinkler-and-the-lawn
The sum of the interior angles of regular polygons
The students will construct triangles within regular-sided polygons to determine the sum of the interior angles. They will then, using statistics, create a linear regression to determine the relationship between the number of sides of a regular polygon and the sum of its interior angles.https://education.ti.com/en/activity/detail/the-sum-of-the-interior-angles-of-regular-polygons
Shortest Distances
Students will explore three situations involving distances between points and lines. First, the minimum distance between two points leads to the Triangle Inequality Theorem. Then, the shortest distance from a point to a line is investigated. Finally, students find the smallest total distan...https://education.ti.com/en/activity/detail/shortest-distances
Side Length, Perimeter, and Area of a Rectangle
Explore the effects of changing base (or height) of a rectangle on it's perimeter and area.https://education.ti.com/en/activity/detail/side-length-perimeter-and-area-of-a-rectangle
Side-Side-Angle: The Ambiguous Case
Experiment with segment lengths and angle measures.https://education.ti.com/en/activity/detail/sidesideangle-the-ambiguous-case
Similar Figures
Observe what happens to ratios of pairs of side of rectangles and triangles.https://education.ti.com/en/activity/detail/similar-figures
Putting limits on Pi
This activity has the students calculate the perimeter of inscribed and circumscribed regular polygons about a circle and then use the calculated values to determine pi.https://education.ti.com/en/activity/detail/putting-limits-on-pi
Triangle Inequality Theorem
Given the measures of any three segments, will you always be able to make a triangle?https://education.ti.com/en/activity/detail/triangle-inequality-theorem
Proving the Pythagorean Theorem - President Garfield's Proof
This is the same proof that is found on the TI-Exchange website for the 84 plus, but I modified it for the Nspire handhelds.https://education.ti.com/en/activity/detail/proving-the-pythagorean-theorem--president-garfields-proof
Triangle Midsegments
Investigate the relationships between a triangle and the similar triangle formed by one of the triangle's midsegments.https://education.ti.com/en/activity/detail/triangle-midsegments
Transformers
Students explore a special subset of the transformations of a square called the symmetry group.https://education.ti.com/en/activity/detail/transformers
Patterns in Area - Impact of Changes in Length and Width
Students will explore what happens to the area of a rectangle if you double the length and width.https://education.ti.com/en/activity/detail/patterns-in-area--impact-of-changes-in-length-and-width
Transformations With Lists
Students use list operations to perform reflections, rotations, translations and dilations on a figure, and graph the resulting image using a scatter plot.https://education.ti.com/en/activity/detail/transformations-with-lists_1
The Tale of Two Tangents
This activity allows students to investigate the relationship between the angle formed by two tangents to a circle and the arcs they intercept.https://education.ti.com/en/activity/detail/the-tale-of-two-tangents
Derivatives of Trigonometric Functions
Students will use the graph of the sine function to estimate the graph of the cosine function. They will do this by inspecting the slope of a tangent to the graph of the sine function at several points and using this information to construct a scatter plot for the derivative of the sine.
