isosceles triangles summary

Summary - If two sides of a triangle are equal, the angles opposite to them are equal. If two angles of a triangle are equal, the sides opposite to these angles are equa..

Triangles are classified on the basis of the lengths of their sides as scalene, isosceles, or equilateral triangles. When any two sides of a triangle are equal it is called as an isosceles triangle . The unequal side is called its base and ..

Construction of an angle equal to a given angle. Bisecting an angle To construct angles 60 o , 120 o and 30 o . To construct angles 90 o , 45 o and 135 o . To construct angles 75 o and 105 o . Drawing the perpendicular bisector of line segment AB. Constructing a perpendicular to a line f..

Which of the following can be the side lengths of an isosceles triangle? => 7, 7 and 7 or 9, 5 and 9 or 4, 5 and 6 or 5, 6 and 7..

Summary - In a triangle the line joining a vertex to the mid point of the opposite side is called a median. The three medians of a triangle are concurrent at a point called the "Centroid". The perpendicular from a vertex to the opposite side is called the "altitude". T..

Which one of these is not an isosceles triangle? => Figure.2 or Figure.1 or Figure.3 or Figure.4..

SAS Axiom: If two triangles have two sides of one equal to two sides of the other, each to each, and angles included by these sides are equal, then the triangles are congruen..
