## What type of construction is illustrated in the figure?

## What is a construction in math?

What are constructions? Constructions are **accurate drawings of shapes, angles and lines in geometry**. To do this we need to use a pencil, a ruler (a straight-edge) and compasses. The basic constructions are perpendicular bisector and angle bisector.

## What is construction in math year 7?

Students are learning about Constructions at this point in Year 7 because **it is a fun Geometry topic which contrasts with the Geometry they will have learnt at Primary School**. It also serves as a chance for students to learn how to use a pair of compasses.

## What is the geometric construction of angles?

To construct an angle with any degree of measure, we need to **make use of a geometric tool called a compass**. Once a ray is drawn, a compass is used to mark arcs according to any measured radius. These arcs intersect each other at various points which form perpendicular lines that make an angle.

## What are the steps of construction in mathematics?

Step 1: Draw a line of any length, Mark a point A on the line, and consider it as a starting point of line segment. Step 2: With the help of a ruler, set the pointer of the compass 5 cm apart from the pencil's lead. Step 3: Place the pointer of the compass at point A and draw an arc on the line with a pencil.

## Which one is the correct construction for a perpendicular bisector?

The steps for the construction of a perpendicular bisector of a line segment are: Step 1: Draw a line segment PQ. Step 2: Adjust the compass with a length of a little more than half of the length of PQ. Step 3: Place the compass pointer at point P and draw arcs above and below the line.

## Frequently Asked Questions

#### What is a construction in geometry?

What are constructions? Constructions are **accurate drawings of shapes, angles and lines in geometry**. To do this we need to use a pencil, a ruler (a straight-edge) and compasses. The basic constructions are perpendicular bisector and angle bisector.

#### What is the ruler and compass construction?

In geometry, straightedge-and-compass construction – also known as ruler-and-compass construction, Euclidean construction, or classical construction – is **the construction of lengths, angles, and other geometric figures using only an idealized ruler and a pair of compasses**.

## FAQ

- What is an example of a perpendicular bisector?
A perpendicular bisector is a line, line segment, ray, or plane that divides a line segment into two equal pieces and intersects the bisected line segment at a right angle. Examples are
