#### Section Formula

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

Using this applet, you can find the coordinates of a point lying between two points. You can also find midpoint of a line segment using this applet.

#### Perpendicular from Center to a Chord

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

Using this applet, one can understand the relationship between the perpendicular drawn from the center of the circle to the chord.

#### SSA-Axiom

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

This applet shows SSA (side side angle axiom) is not sufficient to prove congruency.

#### Cone

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

This applet shows the net of cylinder. The surface area of a cylinder can be found by breaking it down into three parts; the two circles that make up the ends of the cylinder and the side of the cylinder, which when ...

#### Similar Triangles

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

This applet shows the similar triangles. Two triangles are similar if the only difference is size. We can make similar triangles bigger or smaller, but keeping its basic shape.

#### Properties of Chord

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

This applet shows chords which are equidistant from the center of a circle are equal in length a equal chords are equidistant from the center.

#### Chord and Tangent

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

This applet shows that the angle made by a chord with a tangent at the point of contact is equal to the angle formed in the corresponding alternate segment.

#### 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.
