#### Tangents to a Circle

(National Council Of Educational Research And Training (NCERT), 2016-09)

In this applet, observe that the radius of circle is always perpendicular to the tangent.

#### Equations of a Circle

(National Council Of Educational Research And Training (NCERT), 2016-09)

This applet shows how the change in the coordinates of center changes the position of the circle.

#### Circle

(National Council Of Educational Research And Training (NCERT), 2016-02)

In a circle, the region above the chord and between the arc is called a segment of a circle. The piece of a circle between two points of a circle is called arc. This applet helps illustrate these concepts.

#### Cylinder

(National Council Of Educational Research And Training (NCERT), 2016-09)

This applet can be used to explore the net of a cylinder and its surface area formula.

#### Angle Subtended by an Arc of a Circle

(National Council Of Educational Research And Training (NCERT), 2016-09)

This geogebra applet helps to investigate what relation does the angle subtended by an arc at center of the circle have when the same arc subtend an angle at any point on the circumference of the circle.
