Types of Angles Quiz

Acute Angle
- Measures less than 90 degrees.
- Example: 45 degrees.
Right Angle
- Measures exactly 90 degrees.
- Often represented by a small square in the corner of the angle.
Obtuse Angle
- Measures more than 90 degrees but less than 180 degrees.
- Example: 120 degrees.
Straight Angle
- Measures exactly 180 degrees.
- Appears as a straight line.
Reflex Angle
- Measures more than 180 degrees but less than 360 degrees.
- Example: 270 degrees.
Full Angle (Complete Angle)
- Measures exactly 360 degrees.
- Represents a full rotation.
Complementary Angles
- Two angles whose sum is 90 degrees.
- Example: 30 degrees and 60 degrees.
Supplementary Angles
- Two angles whose sum is 180 degrees.
- Example: 110 degrees and 70 degrees.
Adjacent Angles
- Two angles that share a common side and vertex but do not overlap.
Vertical Angles
- Opposite angles formed by the intersection of two lines.
- Are always equal in measure.

Acute Angle: Measures less than 90 degrees (e.g., 45 degrees).
Right Angle: Measures exactly 90 degrees, often indicated by a small square at the corner of the angle.
Obtuse Angle: Measures more than 90 degrees but less than 180 degrees (e.g., 120 degrees).
Straight Angle: Measures exactly 180 degrees, appearing as a straight line.
Reflex Angle: Measures more than 180 degrees but less than 360 degrees (e.g., 270 degrees).
Full Angle: Also known as a complete angle, measures exactly 360 degrees, representing a full rotation.

Complementary Angles: Two angles that add up to 90 degrees (e.g., 30 degrees and 60 degrees).
Supplementary Angles: Two angles that sum to 180 degrees (e.g., 110 degrees and 70 degrees).
Adjacent Angles: Two angles that share a common side and vertex but do not overlap.
Vertical Angles: Formed by the intersection of two lines; these angles are opposite each other and are always equal in measure.

Acute Angle: Measures less than 90 degrees, characterized by a sharp and narrow appearance.
Right Angle: Measures exactly 90 degrees; often depicted by a small square in the corner of the angle.
Obtuse Angle: Measures more than 90 degrees but less than 180 degrees, resulting in a wider form compared to a right angle.
Straight Angle: Measures exactly 180 degrees, forming a straight line.
Reflex Angle: Measures more than 180 degrees but less than 360 degrees; appears to "bend back" and is larger than a straight angle.
Full Angle (Complete Angle): Measures exactly 360 degrees; signifies a complete rotation around a point.
Complementary Angles: Two angles that, when added together, equal 90 degrees; for example, 30 degrees and 60 degrees are complementary.
Supplementary Angles: Two angles that sum up to 180 degrees; an example is 120 degrees and 60 degrees.
Adjacent Angles: Two angles sharing a common vertex and side without overlapping; can be complementary or supplementary based on their measures.
Vertical Angles: Formed when two lines intersect; the angles opposite each other are always equal in measure.

Understanding various types of angles is fundamental in geometry, serving as a foundation for grasping more complex concepts and shapes.
Each angle type has distinct properties that are crucial for solving geometric problems effectively.
