#### Set squares.

There are two triangular shaped instruments called set-squares

n the geometrical box. These are usually made of thin transparent plastic sheet.

In one, the angles are of 90, 45, 45 and in the other, the angles are 30, 60, 90. The set-square in which the angles are of 300, 60 and 90 is called the 30Â° set-square and the set-square in which the angles are of 900, 450 and 450 is called the 45Â° set square. Two perpendicular edges in these set-squares are usually graduated, one in centimetres and the other in inches.

Set-squares are used to draw parallel and perpendicular lines. They can also be used to construct specific angles of 30Â°, 45Â°, 60Â° and 90Â°.

#### Let us construct an angle of 45Â° using a set-square:

Step-1: Place 45Â° set-square on a sheet of paper.

Step-2: Hold the set-square firmly with one hand and with other, draw two rays OA and OB along the edges using a sharp pointed pencil from the vertex of 45Â° angle of the set-square. The angle so formed is the required 45Â° angle.

Note: Similar steps can be used to construct an angle of 30Â° or 60Â° or 90Â° by choosing the appropriate set-square.

#### Perpendicular Lines

Two lines are said to be perpendicular if one of the angles formed by them is a right angle (or 90Â°). lines PQ and RS are perpendicular to each other at the point O because angle ROQ = 90Â°.

We write RS êž± PQ.

### Class 6 Maths Exercise 14.2 Important Questions

### Why it is called Set Square?

It could also be that the “set square” normally comes from a “geometry set” (a set of rulers/tools), so it is the “set square” the “square-making tool from the set”.

### What is the use of set squares?

A set square or triangle (American English) is an object used in engineering and technical drawing, with the aim of providing a straightedge at a right angle or other particular planar angle to a baseline.

### What are the two types of set square?

There are two main types of set square. One has an angle of 450 and the other 300 /600 degree angles. The 450 set square also has a 900 angle. This can be used for drawing vertical lines.

### How do you divide a line with a set square?

To divide a line with a set square these are steps:

(i) Choose the work-piece that you want to divide.

(ii) Choose how many sections you want to make.

(iii) Draw a diagonal line above the line being divided.

(iv) Mark out equal points along the diagonal line.

(v) Use a square / 900 angle to draw lines from the points on the diagonal line down to the original work-piece.

Note: Two segments (or rays) are said to be perpendicular if the lines containing them are perpendicular.
