Special Segments in Triangles
In this activity, students construct medians, altitudes, angle bisectors, and perpendicular bisectors of triangles. They then drag the vertices to see where the intersections of the segments lie in relation to the triangle, and they measure distances to identify relationships. They see that the i...https://education.ti.com/en/activity/detail/special-segments-in-triangles_1
Rhombi, Kites, and Trapezoids
Students discover properties of the diagonals of rhombi and kites, and the properties of angles in rhombi, kites, and trapezoids.https://education.ti.com/en/activity/detail/rhombi-kites-and-trapezoids_1
Geometry: Exploring Quadrilaterals
Drag the verices of a quadrilateral and build the different types; focus on the properties of these different figures, and finally put it all together to identify different quadrilaterals from their properties.https://education.ti.com/en/activity/detail/geometry-exploring-quadrilaterals
