Hello friend’s,today I am going to discuss the important topic for grade IV of karnataka education board which are geometry,geometry help, geometric figures, attributes. So today we will start the brief discussed about that topic.
Let’s start with definition of Geometry. You know friend, geometry is very important set of topic for math students. By geometry we can make a line, triangle, circle, angle etc. These are the applications of the geometry. By geometry we can solve very big problems in short way.
Let’s start with line what is line in geometry? In geometry line has three properties.
Line is straight (no curve),
Line has no thickness
Line can be extended in both directions without end.
Various types of lines:includes Straight line, Parallel lines, Perpendicular line.
Let‘s discuss the another shape:
Quadrilaterals: Quadrilaterals are like a shape which has four sides. Given below are some quadratics with figure:
. Rectangle
.Parallelograms
.Rhombus
.Square
.trapezium
Let’s move on other shape:(To know more about geometrical figures click here)
Circle: A circle is like a closed loop which has a fixed distance from the center point.
Properties of a circle:
Center: a point inside the circle and all points on the circle have same distance from the center point.
Radius: the radius is distance from the circle point and also it’s half of diameter.
Diameter: this is twice of the radius.
Circumference: this is distance all around the circle.
Tangent: a line that is touching the circle at just one point.
Secant: A line that intersect a circle at two points that is secant.
Let’s move on other application:
Triangle: triangle has three sides and three angles.
It’s also called 3-sided polygon.
Triangle properties:
Vertex: vertex is a corner of the triangle and every triangle has three vertices.
Base: any triangle of the bottom side is called base this depends upon area of triangle.
Altitude: altitude of a triangle is the perpendicular from the base to opposite vertex.
Median: when three lines intersects at single point it is called median. This also called cancroids of the triangle.
Interior angles: the three angles on the inside of the triangle at each vertex which angle is called interior angle. (In a triangle the shortest side is always opposite the smallest interior angle.)
Exterior angle: In a triangle, the angle between triangle and the extension of an adjacent side which is called exterior angles. (In a triangle the longest side is always opposite to the largest interior angle.)
Types of triangle: there are seven types of triangles and these have own properties.
Isosceles: in this triangle two sides are equal
Equilateral: in this triangle all sides are equal.
Scalene: in this triangle no sides are equal.
Right triangle: in this only one angle is 900
Obtuse: in this triangle only one angle is greater than 900
Acute: in this triangle all angles less than 900.
Equiangular: in this triangle all interior angles are equal.
So friends that was the basics of the geometry. We hope you have understood the topics very well. To know about grade V topics and Parallel lines, perpendicular lines, geometry wait till next session.
