## What are Angles?

Angles are two straight lines that meet at the same endpoint. The point where the two lines meet is called the corner point. Angles are studied in geometry, an important branch of mathematics. The angle is symbolized as “∠”.

Meanwhile, the angle value is symbolized by the Greek symbol; θ, α, or β. Generally, angles consist of positive angles and negative angles. There are also other popular types of angles such as right angles, obtuse angles, and acute angles.

Angles are used to describe rotations and rotation values for certain parameters. This is implemented in physics. In physics, angles are used to calculate the displacement of objects by calculating the angular displacement.

Angles also have several parts. In general, the angles parts are:

• Arm: Two lines that meet at the same endpoint to form an angle.
• Vertex: Vertex is an angle point.
• Initial Side: Initial side is also called the reference line. This is because the initial side is always used in measurements.
• Terminal Side: The side used to take measurements.

### What are the Types of Angles in Geometry?

In geometry, 7 types of angles need to be studied. Geometry is a branch of mathematics that studies the concepts of 2D, and 3D shapes and their measurements. Because it is related to shape, geometry also studies the points, lines, and plane surfaces that form an object. For this reason, angles are studied in geometry.

Below are the 7 types of angles in geometry.

• Zero Angle: This angle has a value of 0°.
• Acute Angle: Acute angle is an angle with a value of 0°-90°.
• Right Angle: Right angle is an angle with a slope of 90°.
• Obtuse Angle: Obtuse angle is formed from two lines that form an angle of more than 90° to 180°.
• Straight Angle: This angle forms a slope of 180°.
• Reflex Angle: Reflex angle is an angle with a slope of more than 180° to 360°.
• Complete Angle: This angle forms a slope of 360°.

There are other types of angles. Based on the shape of the polygon, angles are divided into interior angles and exterior angles.

• Interior angles are angles in a closed polygon.
• Exterior angles are angles formed outside the polygon. The angle is formed from the extended side of the polygon.

There are also positive and negative angles.

• Positive angles are counterclockwise angles.
• Negative angles are clockwise angles.

### What are the Angle Facts?

Angle facts can help you calculate angles correctly. Here are the angle facts that you should know.

• The angles in a triangle are 180°.
• The sum of the angles in a quadrilateral is 360°, so each angle in the quadrilateral is 90°.
• The angle of a straight line is 180°. If two angles form a straight line, then a + b = 180°.
• Opposite angles have the same value.
• If the exterior angle is symbolized as z and two interior angles are symbolized as x and y, the exterior angle is z = x + y.
• If there are two parallel lines and one line that intersects them, the parallel angles have the same value. Meanwhile, the opposite angle has a different value. Then, the sum of the opposite angles is 180°.

### How to Measure Angles?

A protractor is a tool used to measure angles. The shape of the protractor is semicircular and is usually made of transparent plastic. To measure an angle, you need to place a protractor over the geometric angle image. After that, take angle measurements using the following steps.

• Align the center of the arc with the corner point.
• Then, look at the angle value on the protractor that is parallel to that corner point.

### How to Learn Geometry Angles?

Because angles are a difficult topic for children, learning angles can be done using these fun activities.

• First, make some big letters and ask the children to measure the angles of the letters.
• Draw several 2D objects such as triangles and quadrilaterals. Then, combine several 2D shapes and children can measure the angles of the combination of 2D shapes.
• Angles hunting games can also be an interesting option. You just need to ask children to look for real objects around them and measure their angles. Examples are door and window angles.

## What is the Purpose of the Geometry Angles Worksheet?

The purpose of using a geometry angles worksheet in 7th grade math is to help students understand and practice concepts related to angles, such as measuring, classifying, and finding missing angles in geometric shapes. It helps them develop their geometry skills and build a solid foundation for more complex concepts in higher grades.

A geometry angles worksheet provides exercises that involve identifying types of angles (such as obtuse, acute, and right angles), measuring angles with a protractor, and solving problems involving angles (such as finding missing angles in a shape or triangle).

Teachers can maximize the effectiveness of geometry angles worksheets by incorporating real-life examples and practical applications of angles, as well as providing opportunities for hands-on exploration and problem-solving. Providing clear instructions, scaffolding support, and offering individualized feedback can also enhance student engagement and understanding.

Geometry angles worksheets can also be used as math worksheets for differentiated instruction in 7th-grade math classrooms by providing students with different levels of difficulty to meet their individual learning needs.

### What are the Benefits of Using Geometry Angles Worksheets?

• Geometry angles worksheets can benefit students by providing them with practice and reinforcement of the concepts of angles, allowing them to develop a solid understanding of geometric principles and relationships.

• These worksheets can help students improve their problem-solving skills and spatial reasoning abilities, which are important for success in the field of geometry.
