in an isosceles triangle, if the legs have length L, then the hypotenuse has length L square root of 2
Using Pythagoras's theorem the hypotenuse is the square root of 2 units of length
For isosceles triangle both legs are the same, 10 cm. The hypotenuse is square root of sum of legs squared, = sqrt (10 squared + 10 squared) = 14.1 cm
square root of two.
Equal angles and equal lengths
legs Base and height are equal in langth
Using Pythagoras' theorem for a right angle triangle the hypotenuse works out as the square root of 72 which is about 8.485 units to 3 decimal places
in an isosceles triangle, if the legs have length L, then the hypotenuse has length L square root of 2
The only requirement for an isosceles triangle is that two sides be the same length and one be different. It is possible for an isosceles triangle to have two perpendicular legs. It would be right and isosceles.
A right triangle with legs of 7 and 11 units has a hypotenuse of: 13.04 units.
An isosceles triangle is in effect two right angled triangles joined together and in this case they have bases of 5 units and heights of 2 units so use Pythagoras' theorem to find the hypotenuse which will be the length of one of the equal legs of the isosceles triangle:- 52+22 = 29 and the square of this is about 5.385164807 or 5.385 to 3 dp
isos = equal, skelos = legs. A triangle with two equal legs is isosceles (not icsosceles!).
legs of an isosceles triangle
If you extend the two legs of an isosceles trapezoid until they intersect, you get an isosceles triangle.
in a 45 45 90 right triangle 2 of the legs are equal making it isoceles
The base can have any value between 0 and 8 units.
Actually, it is called an isosceles triangle. In Greek, isosceles means having equal legs: an isosceles triangles has two sides (legs) of equal length.
