Triangles are the polygons with three sides. We say that the triangle is the closed figure with three sides. Now we need to know that the Triangles are classified as per the measure of their lengths of their sides. We say that the triangles which have all the sides of the same measure, then the triangles are called equilateral triangles.
Now we will talk about isosceles triangles: An Isosceles Triangle has two equal sides and the third side is unequal, which works as the base of the triangle. If we look at the special properties of the isosceles triangle, we say:
As isosceles triangle have two lines of same length
As the two sides of the triangle are same, we say that the angles corresponding to the equal sides are also equal.
Also the Median of the isosceles triangle, drawn from non equal side, is also the perpendicular bisector of the non equal side.
As we know that the sum of the three angles of the triangle are equal, thus if one angle of the triangle is known, we are able to find the remaining two angles of the isosceles triangle. Let us see how: If the triangle has one angle = 70 degree, then if we want to find the measure of two angles of the triangle, which are unequal. Let the measure of those angles = x degrees. Now we say that 70 + x + x = 180,
2x + 70 = 180,
2x = 180- 70,
2x = 110,
X = 55, so other two angles of the triangle are 55 and 55 degrees
Similarly, if we know the two equal angles of the triangle, then we double the measure and then subtract it from 180 degrees to get the third angle of the triangle.
Points Shown above are the Special Features of Isosceles Triangles.
Special Features of Isoceles Triangles.
Triangles are classified according to their length of the line segments and as per their angles. We know that if we have the Triangles classified as per the length of their line segments then the triangles are of following types: 1. Equilateral Triangle 2. Isosceles triangle 3. Scalene triangle. Here we are going to study about an Iso...Read More
A Median of a triangle is defined as the line segment which is used to join a vertex of a triangle to the midpoint of the opposite sides of a triangle. There are three vertices present in a triangle, so three medians are present in a triangle. Median value depends on the vertices. There are some properties of An Isosceles Triangle with a median which ...Read More
