Exploring concurrent lines from given surroundings

Interactive activity to introduce concurrent lines using examples from our surroundings.

Objectives
Introduce concurrent lines with examples from surroundings

Estimated Time
10 minutes

Prerequisites/Instructions, prior preparations, if any
The students should know types of lines and the concept of intersection.

Materials/ Resources needed

 * Digital : Computer, geogebra application, projector.
 * Non digital : Paper and pencil

Process (How to do the activity)

 * 1) The teacher can ask the students to explore from their surroundings to identify concurrent lines.
 * 2) She can elicit examples from edges of books, walls, pencil boxes, black board etc.
 * Developmental Questions:
 * 1) What are lines ?
 * 2) What are line segments ?
 * 3) What are intersecting lines and non-intersecting lines ?
 * 4) What are parallel and non-parallel lines ?
 * 5) What are concurrent lines ?
 * 6) What concurrent lines do you identify from your surroundings?
 * Evaluation:
 * 1) Are all types of lines concurrent ?
 * 2) Are parallel lines concurrent ?
 * Question Corner:
 * 1) Differentiate between concurrent lines and collinear points.
 * 2) Give examples of concurrent lines from nature.
