Geometry.
Pythagorean Theorem.
This applet allows students to develop a deeper understanding the Pythagorean Theorem. It shows that the square on the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides. Read the review here.
Congruence Theorems.
This technology allows the user to explore different sets of conditions that determine a shape. Users can explore the conditions that guarantee uniqueness of a triangle, quadrilateral, or pentagon regardless of location or orientation.
Tessellate!
This activity allows the user to deform a triangle, rectangle or hexagon to form a polygon that tiles the plane.
Arc.
This activity allows the user to manipulate the arc length of a circle, which is a portion of a circle.
Central Angle.
This activity allows the user to manipulate the end points on the circumference on a circle to determine the central angle.
Sector.
This activity allows the user to manipulate the end points on the circumference on a circle to determine the area of the sector, which is a portion of the area of a circle.
Volume of a Cone.
This activity allows the user to practice determining the volume of a cone.
Explore Cosine.
This applet is one section of a series of applets to explore right triangle trigonometry. Students are asked questions, make an educated guess, then interact with the applet to determine if their hypothesis was correct.
