Hi friends, In today's article we all are going to discuss about a very important part of cbse syllabus that is angles/relate angles to fractions, Grade IV, geometry help. Before, we move to the topic, it necessary to know about what is angle?which can be used for your Homework help, An angle is defined as a shape, formed by two lines (line one is xy and other is yz and their meeting point is y) or rays diverging from a common point.
Now we are discussing about the Attributes and measurement of angles:- Attributes (Vertex, Legs, Interior, and Exterior) are nothing but the parts of an angle. From the study of these attributes it is easy to understand an angle.
Vertex: The common point at which the two lines or rays are joined is called vertex. If xy and yz are two lines then the vertex point is y and vertex of the angle is xyz.Get further details on fraction here,
Legs: Legs or sides of an angle are the two lines that make it up. From the above, the lines xy and yz are the legs of the angle xyz.
Interior: The interior of an angle is the space by which the angle extending out to infinity.
Exterior : All the space on the plane that is not the interior is called exterior.
Measure of an angle:-In measurement of angle the size of an angle is measured in degrees .When we say the angle xyz we mean the actual angle object. If we want to talk about the size or measure of the angle in degrees we should say the measure of the angle xyz.
Let’s we discuss about the types of angle and these angles are used in mathematics, sciences even in real world problems etc. These angles are explained one by one in below:
Acute Angle: Acute Angle is an angle that is less than 90°.
Right Angle: Exact 90° angle is called right angle.
Obtuse Angle: Obtuse Angle is an angle that is greater than 90° but less than 180°.
Straight Angle: Exact 180° angle is called Straight Angle.
Reflex Angle: Reflex Angle is an angle that is greater than 180°.
Now we are taking some examples: - Let the values of angles a, b, c, d, e and f are 310,
90.50, 900, 1300,370,42.80 respectively. Now from these values of angles the Acute Angles is a, e and f, Obtuse Angles is b and d, right angle is c. Like this we find all the angles.
Now I am telling you something about Pairs of Angles. Pairs of angles are created when parallel lines get crossed by another line which is called a Transversal. These pair of angles has special names and their names are vertical angles, corresponding angles, alternate interior angles, alternate exterior angles, consecutive interior angles.
Lastly I am telling you one more angle that is Angles around a point. Angles around a Point are a 3600 angle and made a circle. For example 53°, 80°, 142°, 85° are the values of angles. When we add these then the sum is 3600.
53°+ 80°+142°+ 85°=3600
From the above discussion I hope it would be help you to understand Angles/relate angles to fractions, Grade IV, geometry and if anyone want to know about Factors and products then they can refer to internet and text books for understanding it more precisely.Read more maths topics of different grades such as Decimals and Place Values in the next session here.
