Types of Angles Class 5 Maths

Mathematical types of angles: Each angle has a unique measure and is formed when two rays or lines intersect at a place. Acute, obtuse, right, reflex, and straight angles can all be used to describe these angles of various measurements. Angle pairs come in a variety of shapes and sizes. Let's take a closer look at the various points of view.

Acute Angle

Less than 90 degree angles are referred to as acute angles. A smaller than 90° angle is created when two rays cross at a vertex or a point, creating an acute angle. A few instances of sharp angles are 20, 30, 45, and 60 degrees. PQR is an acute angle, as can be seen by looking at the diagram.

Right Angle

When the angle created by two rays is exactly 90 degrees, a right angle is created. It is also known as a 90-degree angle due to its unique definition.

Angle AOB is referred to as a right angle since it has a 90 degree angle. A square between the two rays is always used to indicate a correct angle.

Obtuse Angle

Greater than 90 degrees but less than 180 degrees is an obtuse angle.

In the diagram, the angle formed by the rays PQ and QR is acute.

Obtuse angles include those of 110°, 130°, 145°, and 165°.

Straight Angle

A straight angle is, as its name suggests, a straight line where the angle formed by two rays is precisely 180°. The two rays are directly across from one another. A straight angle can be created by joining two adjacent right angles together, or by joining two right angles together. In the diagram, ABC is a straight angle or a 180° angle.

Reflex/Mirror Angle

An angle that is greater than 180 degrees but less than 360 degrees is referred to as a reflex angle. The reflex angle in the diagram is DEF. Reflex angles include those of 210°, 250°, and 310°.

Lessons-Worksheets-Question Papers-CBSE Class 2 English CBSE 2nd Class English – One and Many In this blog, we share the spelling rules used in the concept of One and Many. When there is only one of a naming word (noun), it is said to be a singular noun . When a noun shows more than one, it is said to be in the plural . We can add –S, -es, -ves or ies to show that there is more than one noun. For example, we say many birds, four biscuits, six brushes. But for the students of Class 2 , it’s very difficult and confusing to understand where to use s , es, ves or ies in the form of many. Don’t worry, it looks difficult, but it is very easy as in grammar each concept has a set of rules that need to practice. Noun ending with –s, -x, -o, -sh, -ch, and –ss form plurals by taking –es. Look at these pairs of words: Bus – Buses Brush – Brushes Continue ..... Click here ...

Magnetic and non-magnetic material Class 6 Science

Magnetic and non-magnetic material Class 6 Science A magnet is a substance that is drawn to certain magnetic materials like iron, cobalt, and nickel. Magnets have the ability to draw iron to them. Natural magnets are rocks that naturally draw iron. Non-magnetic materials include things like wood, rubber, coins, feathers, leather, etc. that are not drawn to iron. Magnet characteristics It pulls magnetic materials, such as iron. The magnet's two ends are referred to as its poles. The magnet's diametrically opposed poles are drawn together. Heating, hammering, or dropping causes it to lose its characteristics. On the basis of properties types of Magnets Temporary magnets are those magnets that are magnetic for only a little duration. Typically, iron, cobalt, or nickel are used to make them. When they are close to the powerful magnet, they act like a magnet. When they are yanked away from the powerful magnet, they stop being magnetic. Permanent magnets are magnets that have magne...
