Supplementary angles are two angles whose sum is 180°. For example, ∠AOB = 120° and ∠BOC = 60° are supplementary, as their total is 180°. They are often used in linear pairs. class 6 Mathematics Textbook Chapter 2 question answer class 6 ...
Triangles can be classified by their angles as acute (all angles < 90°), right (one angle = 90°), or obtuse (one angle > 90°). These classifications help in understanding triangle properties and solving related problems. class 6 Mathematics Textbook Chapter 2 ...
Angles can be compared by superimposing them or using geometric tools like folding paper. By matching vertices and arms, one can visually determine which angle is larger or smaller, without measuring their degrees directly. Class 6 Mathematics Ganita Prakash Lines and ...
A reflex angle is greater than 180° but less than 360°. Examples in real life include the rotation of clock hands past 180°, a full swing in motion, or rotating objects like windmills. Class 6 Mathematics Ganita Prakash Lines and Angles Class ...
