do you want to know the area in a isosceles triangle or what?

For all triangles: area = 1/2 * base * height

To find the circumradius of an isosceles triangle, the formula is:1/8[(a^2/h)+4h]in which h is the height of the triangle and a is the base of the triangle.

Ok to find the area of an isosceles triangle: Find the height first, to do this use this formula: Height = Square root ( one side square - half the base square) Now that you have the height you can calculate the area by the use of this formula: Area = (1/2)(base)(height) This will give you the surface area of an isosceles triangle. Lets do an example: You have a triangle that has two sides that measure 24 meters and a base of 20 meters. Using the formula above for height you will get a height of 21.8 meters Now use the formula above to find the area and it will give you an area of 218 meters square

Area of any triangle is: 0.5*base*perpendicular height

Area of isosceles triangle: 0.5*5*7 = 17.5 square cm

What is the length of a leg of an isosceles right triangle if it is area is 72 square inches?

Area of the right isosceles triangle: 0.5*16*16 = 128 square units

An equilateral triangle is a special type of isosceles so an isosceles triangle can not be described as an equilateral triangle so, any equilateral triangle can be an isosceles triangle but an isosceles triangle can not be an equilateral triangle

An acute triangle can be an isosceles triangle, but it doesn't have to be. An isosceles triangle can be an acute triangle, but it doesn't have to be.

Use the distance formula to calculate the distances between the three vertices. If they are all different, the triangle is scalene, if only two are the same, the triangle is isosceles, and if they are all the same, the triangle is equilateral.
