Q1. What do you understand about elementary shapes ?
The Chapter of Class 6 Maths which is The Elementary Shapes very important as they will be introduced to lines, angles and triangles. They will learn the types and the properties of the elementary shapes. The students will learn about a straight line which is starting from a point and will end at a fixed point. The formation of angles is by joining two line segments and the measure of angle by protractor. These are the basic geometry and the students have to learn with full attention.
Q2. What are the basic geometrical ideas?
Geometry is the study of the various shapes and their positions and measurement of the same. The basic geometrical ideas give an idea of the basic terms used. Some of them are;
The point gives a definite location that cannot be moved.
The line is a collection of points.
A ray is a line that has a fixed point and can be indefinitely extended from the other direction.
A part of a line that has a definite length is called a line segment.
A plane is a surface of any solid that can be flat or even curved.
Collinear and non-collinear points If three or more points lie in the same line is collinear and if three or more points do not lie in the same line are non-collinear points.
The curve is a continuous line without any sharp edges.
Polygons are made of the line segments which are connected.
Angles are formed by the joining of the two rays at a point.
A triangle is a closed plane surface with three lines segments.
Q3. What is an angle?
An angle is formed by two different rays which are joined at the point. If you are taking two rays namely AB and BC and if they are made to join at the vertex B then the angle formed can be named angle ABC. The middle letter will represent an angle. Students in Class 6 Maths will be learning different types of angles and their construction. The details of the chapter can be well captured in Vedantu from NCERT solutions. The explanations are given in easy steps and comprehensively structured.
Q4. Why should we not compare line segments by mere observation?
The two-line segments cannot be compared by mere observation. Sometimes it might be seen as the two are of the same length but even a slight difference will make a difference in the value and the numerical might go wrong. The mathematical calculation should be accurate and there is no guesswork. Especially when you are working on a geometrical topic you should be sure that your pencils are sharp so your value is perfect.

Q5. What are the properties of parallelogram and rectangle?
The main properties of a parallelogram are that;
Opposite sides are parallel and equal to each other, opposite angles are equal, diagonals bisect each other if one angle is 90 degrees then all the other angles will be 90.
A parallelogram is divided by the diagonal into two congruent triangles.
Rectangle has all angles as the right angle.
Opposite sides are equal.
Diagonals are equal and bisect each other.
Every rectangle has at least one right angle and it is a parallelogram.
Students should be thorough with these properties and the differences. They should develop conceptual knowledge from the start of the chapters.
