Types Of Angles – (Acute, Right, Obtuse, Straight, Reflex, Complete Angles)
What is an Angle Angles are formed by two rays or lines called the arms or sides of the angle, sharing a common endpoint, called the vertex of the angle. Types of angles There are various types of angles. The angles can be classified into two main types. Basis on their measure or magnitude. Based […]

Acute Angle When two rays are joined together at a common point, an angle is formed. Definition: Acute angle: A angle whose measure is more than 0 degree and less than 90 degree is called a acute angle. ∠AOB is a acute angle, it’s measure 45º, which is less then 90 degree and more then […]

Angle – Definition – Geometry Definition: In plane geometry, angles are formed by two rays or lines called the arms or sides of the angle, sharing a common endpoint, called the vertex of the angle. Angle Symbol An angle is represented by symbol ∠ Angles are measured in degree, which is unit of angle using […]

Convex Polygons: Definition – Examples and Properties All polygons is either convex or concave. A polygon will be convex or concave, it depends on the measure of their angles. If the measures of all interior angles is less 1800 than the polygon is convex, otherwise the polygon is concave. […]

Polygon – Interior and Exterior & Central Angles Interior angle of a regular polygon A regular polygon has all the interior angles same in measure, and all interior angles of polygon formed by each pair of adjacent sides. When a polygon has n sides n vertices and n interior angles. Interior angle = 1800 – Central angle […]

Cartesian Coordinate System Cartesian Coordinate system developed in seventeenth century by Rene Descartes the great French philosopher and mathematician. Cartesian Coordinate system, also called rectangular Coordinate system and used to position of points on a two dimensional or three dimensional plane. Let’s briefly learn about Cartesian Coordinate system. Cartesian Coordinate plane The plane is called Cartesian plane […]

Theorem The perpendicular from the center of a circle to a chord bisects the chord. Given: A circle with center O, AB is chord of a circle and OC perpendicular from the center to the chord AB. i.e. OC ⊥ AB therefore ∠OCA and ∠OCB Both angles are 900. To prove: AC = CB (C is the mid point of chord AB) […]

What is an Acute Triangle: Definition, Formula and Properties In geometry, a triangle is a polygon with three sides, three vertices and three interior angles. In other words a triangle is a closed two dimensional plane figure with three sides and three angles. Triangles are classified on the basis of their sides and angles. There […]
