The size of an angle directly impacts the properties of geometric figures. In triangles, for example, the sum of the interior angles is always 180°, and each angle’s size classifies the triangle as acute, obtuse, or right. The size of angles also determines the symmetry of shapes, affects the congruency of angles, and plays a role in constructing proportional shapes. Understanding angle sizes is key to solving geometric problems and designing various figures in geometry.
A reflex angle is an angle greater than 180° but less than 360°, like a rotation of 270°. Real-life examples include the hands of a clock past 6 o’clock, windmill blades rotating more than half a turn, or doors opening beyond 180°.

To compare two angles without a protractor, one method is superimposition. Place one angle on top of another so the vertices and arms align. The larger angle will cover more area, while the smaller angle will not overlap entirely. Alternatively, folding paper or using a transparent circular sheet caRead more
To compare two angles without a protractor, one method is superimposition. Place one angle on top of another so the vertices and arms align. The larger angle will cover more area, while the smaller angle will not overlap entirely. Alternatively, folding paper or using a transparent circular sheet can help estimate which angle is larger by matching the angles and checking for any differences. This method is effective in comparing angles geometrically without measurement tools.
A ray is a portion of a line that starts at an endpoint and extends infinitely in one direction. For example, ray AB starts at A and extends beyond B. Unlike a line segment, which has two fixed endpoints, a ray has only one endpoint and no measurable length. Examples include a torch’s beam or sunligRead more

An angle's size is determined by the rotation between its arms around the vertex. This rotation is quantified in degrees, where a full circle is 360°, a straight angle is 180°, and a right angle is 90°.

An angle’s size is determined by the rotation between its arms around the vertex. This rotation is quantified in degrees, where a full circle is 360°, a straight angle is 180°, and a right angle is 90°. Using a protractor, one arm aligns with 0°, while the other intersects the scale, providing the angle’s measure. This measurement concept is crucial for comparing angles, constructing shapes, and solving problems in geometry.
