Isosceles Triangle
An Isosceles triangle is a unique kind
of triangle whose properties are often used in geometry.
The picture of an Isosceles triangle is shown below. An
Isosceles triangle can also be called an acute Isosceles
triangle if all angles of the Isosceles triangle are less than
90 degrees. If one of the angles of an Isosceles triangle is an
obtuse angle, then the Isosceles triangle is called an Obtuse
Isosceles triangle.
Definition of Isosceles triangle
An Isosceles triangle is a triangle which
two sides are of the same length (given by S) and the two
angles opposite where the two equal sides meet are also equal
(given by x). That means Isosceles triangles can be defined in
two ways. The first way to define an Isosceles triangle is by
two equal size. When two sides of a triangle are equal, you
have an Isosceles triangle. You can then use the properties of
Isosceles triangles to solve geometry problems such as two
equal angles.
Alternatively, if you define a triangle by
two equal angles, you will have yourself an Isosceles triangle
as well since with two equal angles the sides are forces to be
equal automatically. So, given two equal angles, you can use
the other property of an Isosceles triangle which is two equal
sides.
