Acute Angles

Acute angles are those that measure less than 90 degrees. These angles are common in many geometric shapes, such as triangles. Understanding acute angles is essential for solving various geometric problems involving triangles and polygons.

• Characteristics: Less than 90°
• Example: A triangle where all angles are less than 90° is known as an acute triangle.

Right Angles

Right angles measure exactly 90 degrees. They are fundamental in the construction of figures and structures, ensuring perpendicularity.

• Characteristics: Exactly 90°
• Example: The corners of a square or rectangle.

Obtuse Angles

Obtuse angles are those measuring between 90 and 180 degrees. They add complexity to geometric figures and require a detailed understanding.

• Characteristics: Greater than 90°, but less than 180°
• Example: The angle opposite the acute angles in an obtuse triangle.

Straight Angles

Straight angles measure exactly 180 degrees. They represent the concept of linearity.

• Characteristics: Exactly 180°
• Example: A straight line when looking at the joining of two opposite rays.

Reflex Angles

Reflex angles are those measuring between 180 and 360 degrees. These angles usually appear in circular or rotational contexts.

• Characteristics: Greater than 180°, but less than 360°
• Example: Outside angle in rotational movement.
