Providing you know the length of its base and the lengths of its two equal sides, treat it as being two right angled triangles joined together by halving the length of its base.
Then use Pythagoras' theorem to find its height.

When can the leg of an isosceles triangle be used as the height of the triangle?
Yes if the isosceles triangle is a right isosceles triangle because that leg opposite the hypotenuse is the height
How do you find height of isosceles triangle if you only know the length of equal sides and the base?
i can
You know base and angles how do I find height of isosceles triangle?
Use the sine rule to work out one of the sides. (a/sina = b/sinb = c/sinc) Then as it is an isosceles triangle the perpendicular dropped from the apex will (a) bisect the base and (b) form a right angle with the base. Now you know one side and the hypotenuse of a right-angled triangle and you use Pythagoras (a2 + b2 = c2) to solve the 'other' side of that, which is the height of the isosceles triangle.
What is the formula for the area of an isosceles triangle?
The are of any triangle is calculated by the formula: Area = 1/2 x Base x Height
An A-frame tent is in the shape of an isosceles triangle An isosceles triangle has two equal sides The base of the triangle is 10 ft and the two congruent sides are each 8 ft What is the height?
Use Pythagoras' theorem: 82-52 = 39 and the square root of this is 6.244997998 or 6.245 feet in height to 3 d.p.
How do you find the base and height of an isosceles triangle?
An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base
When can the leg of an isosceles triangle be used as the height of the triangle?
Yes if the isosceles triangle is a right isosceles triangle because that leg opposite the hypotenuse is the height
What is the circumradius of an isosceles triangle?
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.
How do you find height of isosceles triangle if you only know the length of equal sides and the base?
i can
What is hypotenuse in an isosceles triangle?
Only a right triangle has a hypotenuse. An isosceles triangle can be a right triangle but it doesn't have to be. If it's not, then it doesn't have a hypotenuse.
Find the area of an isosceles triangle?
For all triangles: area = 1/2 * base * height
How can you find the length of the 2 sides of an isosceles triangle when you know the base and the height?
By using Pythagoras' theorem.
How do you find the base of an isosceles triangle if you know the angles and the height?
well it seems to me that i don't have a CLUE what your talking about !
What is the formula to find the area of an isosceles triangle?
For all triangles: area = 1/2 * base * height
The triangle at the right is an isosceles triangle. if?
legs Base and height are equal in langth
What is the Surface area of isosceles 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
How do you find the area of an isosceles tringle?
To find the area of any triangle... divide the length of the base by 2... then multiply the result by the height.
