If you want to calculate the area, any of the three sides can be the base. From the base, you draw a perpendicular line to the third angle, to get the height. The result will be the same (within the limit of drawing accuracy, of course), whatever side you choose as the base.

How do you know what the base of a triangle is?

the base of a triange would be different depending per triangle. an equilateral can be any side, an isosceles would be the side that is different and a scalene would be the longest.


How can you find the height of a triangle if you only have the base?

You can't! If the base is the only side you know, you'll need two angles to define the triangle entirely


How do you know which measurements are the base and the height of a triangle?

It does not matter. Any side can be the base. Then, the height is the perpendicular distance between that side and the opposite vertex.


Can any side of a triangle be the base of that triangle?

You can pick any side to be the base. It doesn't really matter.


Is a base of a triangle a side?

Yes, a triangle has 3 sides, and the base is one of those.


How do you find the perimeter of a isoscles triangle all you know is the base and height?

-- Imagine what you have if you slice the triangle in half along the height ...-- You have a right triangle. One side of it is 1/2 of the base, and one side isthe height.-- The slanting side is the hypotenuse of the right triangle, and knowing whatyou know about right triangles, you can calculate its length.-- Once you do that, you have the lengths of all three sides of the original triangle,and you can calculate the perimeter.


Can the side opposite of the vertex of a triangle could be the base of a triangle?

Yes, though generally speaking the bottom, horizontal side (if any) of a triangle is called its base.


If the base of an isosceles triangle is 74 what is the measure of the vertex angle?

You can't calculate any angle if all you know is one side of the triangle.


What side that is the bottom of triangle?

Its base.


Which is the base of an isosceles triangle?

Two sides of an isosceles triangle are equal. The base is the other side.


How do you get the area of a triangle without a base?

it depends on the numbers you do get and what type of triangle it is. If somehow you can get it to be a right triangle and you have either the height or the hypotenuse, use the Pythagorean Theorem, A^2 +B^2=C^2... A and B being either the height or base and C being the hypotenuse. (side opposite the right angle is the hypotenuse)The base side of a triangle can be any side of the triangle - the height of the triangle is the perpendicular distance from this side to the opposite vertex.If you do not know the base length, then you must not know the length of any side of the triangle. You need to know one height and two other facts:If you know all three heights of the triangle, then the area can be worked out using:area = 1 ÷ (4 x √(h(h - 1/x)(h - 1/y)(h - 1/z)))wherex, y, and z are the three heights of the triangle; andh = 1/2 (1/x + 1/y + 1/z)If you know the one height of the triangle and the angles at the ends of the base of the triangle, the base length can be worked out by trigonometry to give the area as:area = 1/2(cot A + cot B)h2whereh is the height of the triangle; andA and B are the angles at the ends of the base.


What is the base of isosceles triangle?

the isosceles triangle ahs two equal sides and one different side. The base is the one with the different side.
