By the term triangle we mean that it is a closed polygon which if formed by joining 3 line segments. There are different types of triangles based on the lengths of the line segments.
They are : Equilateral Triangle, isosceles triangle, and scalene triangles. By the term Isosceles triangle, we mean that the triangle which has a pair of the two sides equal. In such a triangle, if we have pair of the sides equal, we say that the pair of the angles which are formed by the pair of sides is also equal. So we come to the conclusion that in the isosceles triangle we have two sides equal and two angles equal. (If you want to get more information about isosceles triangle, Refer this)
If we drop a perpendicular from the angle which is unequal in the isosceles triangle, we observe that this perpendicular is the perpendicular bisector to the line segment which is opposite to this angle. Thus we also called this line as the median of the isosceles triangle.
We further observe that this median, which is also the perpendicular bisector is the line of symmetry of the given isosceles triangle. Any isosceles triangle has only one line of symmetry and this line of symmetry divides the given isosceles triangle into two equal halves. We also call it the mirror half of the triangle. On the other hand an equilateral triangle has 3 lines of symmetry and a scalene triangle has no line of symmetry.
If we need to learn about What are Perpendicular Lines, we can visit the online math tutorial and take the help of the modules based on the above topic in the tutorial. We also have cbse syllabus 2013 online which can be downloaded to understand the pattern of the question paper in the upcoming examination. It guides the students to know about the important questions for the exams and In the next session we will discuss about Equation of Circle.
