A right angle isosceles triangle is then formed which will have two 45 degrees angles and one 90 degrees angle.
Isosceles triangles
1) The hypotenuse side will ALWAYS be the the side w/ the radical 2. 2) So if you want to find the HYPOTENUSE of an ISOSCELES triangle, you MULTIPLY one of the LEGS by the the square root of 2. 3) If you want to find the LEG of an ISOSCELES triangle, you DIVIDE the HYPOTENUSE by the square root of 2. ***** Hypotenuse of an isosceles triangle= one leg divided by square root of 2. ***** Leg of an isosceles triangle= hypotenuse divided by the square root of 2.

Area of the right isosceles triangle: 0.5*16*16 = 128 square units
An equilateral triangle is a triangle with three equal sides. An isosceles triangle is one with two equal sides. So yes, an equilateral triangle qualifies as being an isosceles triangle as well. This is quite similar to the relationship between squares and rectangles, where a square is always a rectangle, but a rectangle isn't necessarily a square.
No. Think of a triangle with two 45o angles. These must be opposite equal sides which in turn form a right angle. Imagine a square divided into 4 by diagonals, forming 4 isosceles right-angled triangles.

its about 5.657. 8 divided by the square root of 2
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
in an isosceles triangle, if the legs have length L, then the hypotenuse has length L square root of 2

Such a triangle is an isosceles (and right), but is sometimes called a square triangle (for historic reasons of the definition of square).
A right angle triangle or an isosceles triangle.
Area of isosceles triangle: 0.5*5*7 = 17.5 square cm
A square!!!! Draw two diagonals. The interior of the square is now four Isosceles triangles.
