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
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
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
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
Transformations: Reflections and Rotations
This activity is designed to be used in a middle-school or high-school geometry classroom. An understanding of labeling points in the coordinate plane is necessary. This is an exploration using reflections to move a polygon about the coordinate plane.https://education.ti.com/en/activity/detail/transformations--reflections-and-rotations
Equations of a Circle
In this activity, the students can be partnered up and will discover how the equation of a circle changes when you move the circle around the coordinate plane.https://education.ti.com/en/activity/detail/equations-of-a-circle
Properties of Parallelograms
Students will manipulate parallelograms to discover the relationships between the sides, angles, and diagonals of parallelograms.https://education.ti.com/en/activity/detail/properties-of-parallelograms_7
Implicit Differentiation Tangent Line Problem

Exploring Transformations
Investigate translating and reflecting shapes in the coordinate plane and observe how the new image is related to the original shape.https://education.ti.com/en/activity/detail/exploring-transformations
Exploring Midsegments of a Triangle
Students will discover the relationships between a midsegment of a triangle and its third side.https://education.ti.com/en/activity/detail/exploring-midsegments-of-a-triangle
Circles - Angles and Arcs
In this activity, students will investigate inscribed angles, central angles and intercepted arcs relationships in circles.https://education.ti.com/en/activity/detail/circles--angles-and-arcs
Alternate Interior Angles
Explore the relationships of the angles formed when two parallel lines are cut by a transversal.https://education.ti.com/en/activity/detail/alternate-interior-angles
The Flag Problem
Students explore the area of a triangle with the base being one of the legs of a right angled trapezoid, and an opposite vertex being a point on the other leg of the trapezoid.https://education.ti.com/en/activity/detail/the-flag-problem
The Geometric Mean
In this activity, students will establish that several triangles are similar and then determine that the altitude to the hypotenuse of a right triangle is the geometric mean between the segments into which it divides the hypotenuse.https://education.ti.com/en/activity/detail/the-geometric-mean_1
The Ladder Problem Revisited
In this activity students explore the locus of mid-point of the hypotenuse of a fixed length geometrically and algebraically and discover that the median a right triangle is equal to half the length of the hypotenuse. Students then prove this property. The problem: A ladder leans upright against ...https://education.ti.com/en/activity/detail/the-ladder-problem-revisited
Pythagorean Triples
Explore Pythagorean triples by dragging vertices to find whole number Pythagorean triples.https://education.ti.com/en/activity/detail/pythagorean-triples
The Pythagorean Theorem—and More
Students construct a triangle and find all angle and side measures. They practice dragging the vertices to form certain types of triangles, and then they confirm the Pythagorean Theorem for right triangles. Moreover, they discover the types of triangle that occur when c2 a2 + b2 or when c2 > a2 +...https://education.ti.com/en/activity/detail/the-pythagorean-theoremand-more
