Discovering the Circumcenter and Centroid of a Triangle
The students will find the circumcenter by constructing perpendicular bisectors of the sides of a triangle. They will also find the centroid by constructing the medians of a triangle and discover that the centroid is 2/3 of the distance from each vertex along each median.https://education.ti.com/en/activity/detail/discovering-the-circumcenter-and-centroid-of-a-triangle
Exploring the Black Box of Quadrilaterals
The exploration will begin with students dragging the quadrilateral given to them about the screen. Initially, they will be asked to simply identify the quadrilateral's type by sight. This will require simply a visual recognition of the quadrilaterals parallelogram, rectangle, square, rhombus, ...https://education.ti.com/en/activity/detail/exploring-the-black-box-of-quadrilaterals
Exploring the Formula for Area of a Triangle: How was it Derived?
This activity is designed to be paperless. The entire lesson is written to be placed in the Nspire. Students will explore how the formula for area of a triangle works and why it works, they will also explore altitudes and medians of triangles.https://education.ti.com/en/activity/detail/exploring-the-formula-for-area-of-a-triangle-how-was-it-derived
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
Triangle Sum Theorem

Finding the Minimal Path to Put Out a Fire
A camper (at position A) must quickly put out a campfire (at position B). The river is represented by the horizontal line segment CD passing through point P. Where should point P be positioned on the river so that the camper will travel the shortest (minimal) path from point A, to the river at po...https://education.ti.com/en/activity/detail/finding-the-minimal-path-to-put-out-a-fire
Investigating the Angles of a Triangle
The following will find the sum of the interior angles of a triangle and the sum of the remote interior angles of a triangle. Students can then change the type of triangle. The student will see that the sum of the interior angles is always 180 degrees. Also, the student will see that the sum of t...https://education.ti.com/en/activity/detail/investigating-the-angles-of-a-triangle
Investigating the Sum of Polygon Angle Measures
In this activity, students will investigate the relationship between the number of sides of a polygon and the sum of the measures of the angles of the polygon.https://education.ti.com/en/activity/detail/investigating-the-sum-of-polygon-angle-measures
