Construction in Maths for Class 7

The Construction Class 7 RS Aggarwal builds on your previous knowledge of shapes and how to draw them. This Chapter will learn how to draw a line segment of a specific length, a line perpendicular to another line, parallel lines, and different kinds of Triangles. The main takeaways of this Chapter are:

• Line Segment - When you take two points on a line, then the part within those two points is called a line segment.

• A Line Perpendicular to A Line Segment - Any line which intersects a line segment at a point and makes 90 degrees is called a line perpendicular to the other line segment.

• Constructing a line that is parallel to another line segment through a point that is not on the line:

a. We will use a ruler and compass only to construct this line.

b. Draw a line AB and take C as a point that is outside of it.

c. Now take a point D on the line AB and join it with C.

d. Keeping D as the center, use a compass to draw an arc of any radius cutting AB at E and DC at F.

e. Now take C as the center and draw another arc with the same radius as the one you used to draw the above arc.

f. Measure line EF with the compass and mark an arc of the same measurement from C to cut the arc at S.

g. When you join CS, it will give you a parallel line to the line segment AC.

• Constructing a Triangle with SSS (all 3 sides are known) criterion

a. Let us say we have to draw a Triangle PQR with PQ = 6 cm, QR = 5 cm, and PR = 9 cm

i. Draw a rough sketch of the Triangle first with the given measurements.

ii. Draw a line segment PQ

iii. Since PR = 9 cms, take P as the center and draw an arc of 9 cms.

iv. Now QR = 5 cms so take Q as the center and draw an arc of 5 cms in such a way that it intersects the arc drawn in the previous step.

v. The point of intersection of both the arcs is the point R.

vi. Join PR and QR to get the required Triangle PQR.

• Constructing a Triangle with SAS (two sides and the included angle is given) criterion

a. Let us say that the Triangle ABC we need to draw has two sides AB = 8 cm, AC = 5 cms, and ∠CAB = 60 degrees.

i. First, draw a rough sketch of the Triangle based on the information given.

ii. Draw a line segment AB = 8 cms.

iii. Now draw a line AX which makes an angle of 60 degrees at A, the line AC will lie somewhere on this ray of the angle.

iv. Now AC = 5 cms so with A as center draw an arc of 5 cms on AX that is the point C

v. Now join BC to get the required Triangle.

• Exercises

a. 17 A - 3 long type questions based on constructing various kinds of line segments.

b. 17 B - 13 long type questions based on constructing Triangles on different criteria.

c. 17 C - 38 questions which are a mix of short and long type answers. They are based on different types of angles and Triangles.

d. Test paper - 18 questions

Preparation Tips for RS Aggarwal Class 7 Maths Chapter 17

• Maths is a hands-on subject, and particularly Geometry and constructions can only be learned by practising as many different kinds of problems as possible. 

• Try to pick out sums from RS Aggarwal Class 7 Maths Chapter 17 which you find difficult and hone your skills in those kinds of problems.

• Always draw a rough sketch of whatever diagram is presented in the RS Aggarwal Solutions Class 7 ch 17 to get an idea of what is being asked.

• Remember all the criteria for Triangles (SSS, SAS, RHS, etc.) and write them down in a note to stick it in your room. This way, you can remember them all quickly.
