Isosceles Triangle Area
Definition: An isosceles triangle is a triangle with two sides that are equal in length.
Any equilateral triangle is also isosceles,
but not every isosceles is equilateral.
- the area of an isosceles triangle can be found using the height and base.
- knowing the length of the side and the base of the isosceles triangle.
- knowing the length of the side and the angle at the apex.
- knowing the base and the angle of the isosceles triangle
Two equal sides are the lateral sides.
The third side is the base.
Properties of an isosceles triangle:
1) The angles at the base are equal in degree.2) Bisectors, medians, heights drawn from equal angles are equal.
The area of an isosceles triangle is calculated by the formula:
where b- this is the base of the triangle,a- side of the triangle.
