A straight angle, measuring 180°, represents a half-circle rotation. It is composed of two right angles, each measuring 90°. For instance, if a straight angle ∠ABC is bisected by ray BD, it creates ∠ABD and ∠DBC, both being right angles. This relationship illustrates the concept of perpendicularity,Read more
A straight angle, measuring 180°, represents a half-circle rotation. It is composed of two right angles, each measuring 90°. For instance, if a straight angle ∠ABC is bisected by ray BD, it creates ∠ABD and ∠DBC, both being right angles. This relationship illustrates the concept of perpendicularity, where two lines intersect to form right angles. Understanding this helps in geometry to construct perpendicular lines or divide angles accurately.
A straight angle is formed when two rays extend in opposite directions from a common vertex, creating a straight line. It measures 180°, which is half a full turn (360°). For instance, the hands of a clock at 6 o’clock or the horizon viewed in a straight line form straight angles. These angles are fRead more

For instance, the hands of a clock at 6 o’clock or the horizon viewed in a straight line form straight angles. These angles are foundational in geometry, often used to define linear relationships, parallel lines, and bisected angles.
Angles are categorized based on their measures: 1. Acute angles: Less than 90° (e.g., 30°). 2. Right angles: Exactly 90° (e.g., the corner of a square). 3. Obtuse angles: Between 90° and 180° (e.g., 120°). 4. Straight angles: Exactly 180°, forming a straight line. 5. Reflex angles: Greater than 180°Read more

5. Reflex angles: Greater than 180° but less than 360° (e.g., 270°).
These classifications help in analyzing shapes, rotations, and geometric constructions.
A ray begins at a fixed point and extends endlessly in one direction, such as sunlight from the Sun. A line extends infinitely in both directions without endpoints, like the horizon. A line segment is a part of a line with two fixed endpoints, such as the distance between two points on paper. TheseRead more

Triangles are classified based on their angles: 1. Acute triangle: All angles are less than 90°. 2. Right triangle: One angle is exactly 90°. 3. Obtuse triangle: One angle is greater than 90°. These classifications are important in geometry because they influence the properties of the triangle, suchRead more
