<u>An angle can be defined as the figure formed by two rays meeting at a common end point</u>. An angle is represented by the symbol ∠. Here, the angle below is ∠AOB. Angles are measured in degrees, using a protractor.
<u>An angle is formed when two lines meet at a </u>
<u>An angle is formed when two lines meet at a shared point</u>. They are measured in degrees, which are represented by the symbol °. There are four important types of angle: acute, right, obtuse, and reflex. A full circle has 360°. If you see an angle of 720°, it means it has rotated twice around a full circle.
<u>Angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle</u>. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles.
<h2>5 Types of Angle</h2>
<h3>1. Acute Angle</h3>
- An <u>acute angle</u> is an angle that measures less than 90 degrees...
- For example, in an equilateral triangle, all three <u>angles</u> measure 60˚, making it an <u>acute</u> triangle. <u>Acute</u> triangle.
- Dividing the right <u>angle</u> will give us two or more acute angles since each newly formed <u>angle</u> will be less than 90˚.
<h3 /><h3>2. Right Angle</h3>
- In geometry and trigonometry, a right angle is an <u>angle</u> of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent <u>angles</u> are equal, then they are <u>right angles</u>.
<h3>3. Obtuse Angle</h3>
- An <u>obtuse angle</u> is a type of <u>angle</u> that is always larger than 90° but less than 180°. In other words, it lies between 90° and 180°.
<h3>4. Straight Angle</h3>
- In Maths, a straight angle is an <u>angle</u> equal to 180 degrees. It is called straight because it appears as a straight line. Basically, as per <u>angles</u> definition in maths, when two rays are joined end to end, they form an <u>angle</u>.
<h3>5. Reflex Angle</h3>
- A <u>reflex angle</u> is any angle that is more than 180 degrees (half circle) and less than 360 degrees (full circle). A <u>reflex angle</u> will always have either an obtuse or an acute <u>angle</u> on the other side of it
