Use the law of cosines (look them up on wikipedia).

How do find the area of an isosceles tringle?
The area of ANY triangle is base x height. The height must be measured perpendicular to the base. In the case of an isosceles triangle, if you know only the length of the sides, you can figure out the height by Pythagoras' Theorem.
How do you figure out the actual area of your tent?
If you know how to find the area of a triangle do the same thing and you will get the same answer.
What does the word equilateral mean?
an equilateral triangle is a triangle in which all three sides are equal.Equilateral means that all the sides in a figure are congruent. Regular polygons are all equilateral.
Can you use Trigonometry if you only know the sides of the triangle?
Do you mean you know the lengths of the sides but you don't know the size of any of the angles ? If that's the situation, then yes. The lengths of the sides tell you everything about the triangle, and they define one and only one unique triangle. With a little bit of trig, you can figure out what the size of each angle has to be.
How do you figure the base of a triangle when you know the dimension of the other two sides?
If it is a right triangle, you can use the Pythagorean Theorem. If you know the angle measures, you can use cosine/sine/tangent.

How do you find the area and perimeter if the figure does not have equal sides?
For the perimeter, you just go round the shape, adding the lengths of each side as you go along. There may or may not be simple formulae of the area for a shape with unequal sides. If all you know is the [different] side lengths then only a triangle has a relatively simple formula for its area. If you also know that some of the sides are parallel, then you can find the area of a rectangle. Then, if you also know the perpendicular distance between the parallel sides, you can do a parallelogram. If, in addition you know which sides are parallel, a trapezium. And so on.

How can it be proved that the circumradius of a triangle is the product of three sides divided by four times the area of the triangle?
We know that R = a/2sinA area of triangle = 1/2 bc sinA sin A = 2(area of triangle)/bc R = (a/2)*2(area of triangle)/bc R = abc/4*(area of triangle)
How do you find the area of a triangle when given 3 angles and the perimeter?
If you know the lengths of 2 sides and the included angle then use: Area of a triangle = 1/2*a*b*sinC
Given is the sides of the triangle then how to find the height and the base?
there is this so called heron theory where you can get the area of any triangle if you know the values of the three sides (you do not need to know the heigth) i do no know if this is true but this can be found by searching the web for the 'heron theorem' good luck
How do you figure area when all 4 sides are different?
You need to cut up your figure into several parts in shapes for which we know how to calculate areas, such as squares, rectangles, and triangles. The area of your figure is the sum of the areas of its parts.
Find the area of a triangle that has a perimeter of 21 inches?
I need to know more about the triangle, such as one or 2 of the angles, whether it is isosceles or equilateral, or whether the lengths share a certain ratio. For example, a triangle of sides 8,8 and 5 (perimeter of 21) will surely have a different area as compared to a triangle of sides 7,7 and 7 (perimeter of 21 as well)
How do you make a triangle when you only know two sides and one angle?
Thats already a triangle if it three sides.
