Rihan can draw an infinite number of lines through a single point, as lines extend endlessly in both directions. A single point determines no specific direction, allowing countless possibilities. Class 6 Mathematics Ganita Prakash Lines and Angles Class 6 Mathematics Chapter 2 ...
Acute angles are smaller than 90°, right angles measure exactly 90°, obtuse angles range between 90° and 180°, and straight angles equal 180°. Identify these based on their degree measurements in the figures. Class 6 Mathematics Chapter 2 Lines and Angles ...
Fold the paper diagonally to form a slanting crease. Open the paper, then fold it again such that the new fold meets the first crease at a 90-degree angle. Ensure edges align properly. Class 6 Mathematics Chapter 2 Lines and Angles ...
Folding perpendicular to a slanting crease creates four right angles at the intersection. Each measures 90 degrees because the creases divide the plane into four equal quadrants, confirming their geometric definition as right angles. Class 6 Mathematics Chapter 2 Lines and ...
Classroom windows often form multiple right angles at corners, typically four per rectangular window. Additional right angles exist in door frames, blackboard edges, desks, and other rectangular or perpendicular structures within the room. Class 6 Mathematics Ganita Prakash Lines and Angles Class ...
A straight angle equals half a full turn, or 180 degrees. A right angle is half of this, formed by a quarter turn, measuring 90 degrees. It’s visually represented as an “L” shape. Class 6 Mathematics Ganita Prakash Lines and Angles Class ...
The two angles are equal if their degree measurements match. Superimposition aligns their vertices and one arm to confirm equality. Folding paper through the angle’s vertex replicates this process visually and effectively. Class 6 Mathematics Ganita Prakash Lines and Angles Class 6 ...
Compare ∠XOY and ∠AOB by measuring their degrees or superimposing. The greater angle has a larger degree of rotation from one arm to the other. Justification depends on precise measurements or visual overlap. class 6 Mathematics Textbook Chapter 2 question answer class ...
Folding creates angles between the fold and paper edges. Use a protractor to measure them. Different folds produce angles of varying sizes, the largest being obtuse or straight and the smallest acute. class 6 Mathematics Textbook Chapter 2 question answer class 6 ...
