An angle is formed by two rays sharing a common endpoint. The rays are called arms, and the common point is called the vertex. For example, ∠ABC has arms BA and BC with vertex B. Class 6 NCERT Ganita Prakash Chapter ...
Angles are fundamental in construction and design for creating accurate measurements and shapes. For instance, right angles are used to construct square corners, and specific angle measurements ensure structural stability in buildings and furniture. Class 6 NCERT Ganita Prakash Chapter 2 ...
An angle bisector divides an angle into two equal parts. It is crucial in geometry for constructing equal angles, finding symmetrical properties, and solving problems related to angle division, such as in triangles. Class 6 Mathematics Chapter 2 Lines and Angles ...
Angles are classified as acute (<90°), right (90°), obtuse (90°–180°), straight (180°), and reflex (>180° but <360°). Examples include a 45° acute angle, a 120° obtuse angle, and a 270° reflex angle. class 6 Mathematics Textbook Chapter 2 question answer class 6 ...
Measure ∠PQR, ∠PQS, and ∠PQT using a protractor. Align it with the vertex (Q) and the respective arms. Note the intersection points on the protractor scale and record the degree values systematically. Class 6 Mathematics Chapter 2 Lines and Angles question ...
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 ...
Three points, A, B, and C, yield three unique lines: AB, BC, and AC. These lines form three angles: ∠ABC, ∠BCA, and ∠CAB. Mark angles with a curve for proper identification. Class 6 NCERT Ganita Prakash Chapter 2 Lines and Angles class ...
The line segments in Fig. 2.4 are LM, MQ, and QR. Point P lies on one line segment, MQ. Points M and Q lie on two line segments, connecting LM-MQ and MQ-QR respectively. Class 6 Mathematics Ganita Prakash Lines and Angles Class ...
