NCERT Grade 7 Mathematics Chapter 10, Practical Geometry deals with construction of lines and geometrical figures. Students have learnt about different shapes and basic drawing of lines and segments. In this chapter, the learning of construction of geometrical shapes extends to drawing of parallel lines and some types of triangles.
Construction Of A Line Parallel To A Given Line, Through A Point Not on The Line, Construction Of Triangles, Constructing A Triangle When The Lengths Of Its Three Sides Are Known (SSS Criterion), Constructing A Triangle When The Lengths Of Two Sides And The Measure Of The Angle Between Them Are Known. (SAS Criterion), Constructing A Triangle When The Measures Of Two Of Its Angles And The Length Of The Side Included Between Them Is Given. (Asa Criterion) And Constructing A Right-Angled Triangle When The Length Of One Leg And Its Hypotenuse Are Given (RHS Criterion) are the main topics covered in this chapter.
Step-by-step demonstration, figures and diagrammatic representation make the learning of construction very easy and interesting to learn. Activities and exercises given at regular intervals; help to maintain the grip on the topic and enhance the learning experience. A part of Geometry, NCERT Grade 7 Mathematics Chapter 10, Practical Geometry will help the students to not only develop a grip of the topic but also master the concepts that will help them to perform better.
