Definition An isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having two and only two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case. They have many properties are exist.Watch Properties of Isosceles Triangle […]

Definition An angle is formed by two rays with a common initial point. The common initial point is called the vertex. The rays forming an angle are called arms or sides of an angle. Angle can be divided into different types on the basis of their measures. The different types of an angle on the […]

Definition Triangle is a plane closed figure with three straight sides and three angles. If two sides of a triangle are unequal, the greater side has greater angle opposite to it.Watch Greater Side Has Greater Angle Videos to learn more. Greater Side Has Greater Angle Theorem: A greater side of a triangle is opposite a greater […]

Definition Triangle inequality theorem states that, the sum of the lengths of any two sides of a triangle is greater than the length of the third side. The applied problems and the proof of theorem are explained at Triangle Inequality Theorem Video , watch it. Triangle Inequality Theorem The statement of the theorem is that, the […]

Definition The two lines which are non parallel always intersect, i.e., they pass through the common point. If three or more lines pass through the same point then they are called concurrent lines and the common point is called the point of concurrency or concurrent point. A median of a triangle is a segment joining […]

Definition The two lines which are non parallel always intersect, i.e., they pass through the common point. If three or more lines pass through the same point then they are called concurrent lines and the common point is called the point of concurrency or concurrent point. These definitions and the properties are described on Point […]

Definition about congruent of triangle The SAS stands for “side, angle, side” and they means that if we have two triangles where we know two sides and the included angle are equal. If the two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are called congruent. This is the congruence […]
