The answer depends on what information you have and what level of mathematics you have reached.
If you have three sides, a, b and c, then let s = (a + b + c)/2 Area = sqrt[s*(s - a)*(s - b)*(s - c)]
Two sides and included angle, a, b and C Area = 1/2*a*b*sin(C)
Two sides and non-included angle, a, b and A (or B) use the sine rule to find the angle opposite the other known side. Use the sum of the angles of the triangle to find the included angle. Then as in previous case.
One side and two angles, a, B and C Since the sum of the angles is 180 you effectively know all 3 angles. Use the sine rule to work out another side and then use the rule for a, b and C.
Equilateral triangle, sides a then Area = [sqrt(3)*a^2]/4
Base, b and height, h: Area = 1/2*b*h
There are other formulae.
|ab|=4 |ac|=5 |bc|=4Let |ab| be the bottom line and draw a line measuring 4cm. Then use your compass and measure on a ruler 5cm. Put your compass on a and draw an arc.Then put your compass at b n mark off 4cm. Wherever these 2arcs meet join them to the bottom line |ab|. Your triangle is now finished.=]
The height of a triangle, is the length of the line that runs from the tip of the triangle to the triangle base and perpendicular to it.
Base times height times 1/2
(the base is the bottom of the triangle and the height is from the top to the base)
It depends on what information is available.
You must have some data regarding the measurements of the triangle in order to calculate the base and the height. Lacking any data, the only way to find them is to measure them.
cause when you make isoceles triangle and cut it by 2 the isoceles will has a equal sides
The bottom edge
A+b+c/2=area
21 inches squared
the mass of it is to multiply the height and width and find your base
The formula for the area of a triangle is:1/2 bx h= half of the base of the triangles the heightHope this helpsMAKE IT SHINE!

There are some formulas for pyramids for area and perimeter. There is also one if you have a 2D pyramid that has, lets say blocks for the base. 0 00 000 0000 Like that. There is a formula without the E, to find out how many 0's there are in the pyramid. Total num.=((base num./2)+0.5)base num. T=((n/2)+0.5)n In this case the base num. is 4 because there are 4 0's on the bottom of the pyramid. T=((4/2)+0.5)4 T=(2+0.5)4 T=(2.5)4 T=10 There are ten 0's in the above pyramid. The area is base * height /2 a the perimeter is all the sides added together.
To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.
It is impossible to find the height of a triangle with just it's base.
Area = 0.5*Base*Height
The relation between the height of a triangle, its base and its area is given by: Area = 0.5 * Base * Height Therefore, we have: Height = (2 * Area)/ Base.
To find the height of a triangle you measure it. It has to be from the middle of the base to the top point.
the height of a triangle is three feet longer than the base. The area of the triangle is 35 square feet. Find the height andbase of the triangle
It is not possible.
An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base
It is found by: base = (area*2)/height
base = (2*area)/height
Area = 1/2 * base * height.
Divide the area by height then you get the base.
