Corresponding Angles – Definition – Examples Two angles that are corresponding are those that are located on the same side of a transversal in identical relative position. They typically result from a transversal cutting two lines, whether they are parallel or not. In other words corresponding angles formed when a transversal line cuts across two […]

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 […]

Similar Polygons Two polygons are similar if they have same shape, but not the same size. Similar polygons are polygons, if their corresponding angles are congruent, and the measure of their corresponding sides are proportional. The ratio of length of their corresponding sides are all in a constant ratio, and their corresponding angles are equal. […]

 Congruent Figures In our daily life we see many congruent objects like as,  (i) Two 2 Rupees, 5 Rupees, or 10 Rupees coins. (ii) Two text books of mathematics of same class.  Two figures or objects are called congruent, when one object cover the other completely and exactly. This means that two books or coins […]

Angle Bisector – Definition -Examples  The angle(interior) bisector of an angle is a line or line segment that divides the angle into two (congruent)equal parts.  The angle bisector is also called the internal angle bisector. In ∠ABC, BD is angle bisector of ∠ABC. In above figure BD is bisect the ∠ABC. ∵ ∠ABC = 900∴ ∠ABD   = 450and ∠DBC = 450 ∠ABD and ∠DBC […]
