Not too sure of your question but a triangle and a hexagon are both polygons
1-360 (1-180 in a traiangle)
It is called an isosceles traiangle.
A triangle only has one altitude which is its perpendicular height.
A Triangle with three equal sides is called a Equilateral Triangle.
I only know that it has R,A,I and O. The other one i dont know
If it is an isosceles triangle then side BC is 15cm and side AC is 15m
Its other leg is sqrt(172 - 112) = sqrt(168) So area of traiangle = 0.5*11*sqrt(168) = 71.29 square units, approx.
All angle in a triangle add up to 180o. In an equilateral triangle, each of the three angles is equal to 60o; in isosceles triangles, two angles are equal; in scalene triangles, none are the same; in right-angled triangles, one of them must be 90o.
Suppose the sides of the triangle are 2x. Drop a perpendicular bisector from the apex to the base. Now consider the half-triangle formed. The hypotenuse is one of the sides of the original triangle, so 2x in length. The base is half the side of the original traiangle, so x in length. So, by Pythagoras, the height2 is (2x)2 - x2 = 3*x2 So height = x*sqrt(3) Then area of the whole traiangle = base*height/2 = 2x*x*sqrt(3)/2 =x2*sqrt(3) This is given as 36*radical 3 so x2 = 36 ie x = 6 So the sides, = 2x = 12 units.
no, the reason why is as follows. The definition of a triangle stipulates that there is exactly 180 degrees inside the three sides. At a right angle the degree is 90. If two of my three angles are both 90 then their sum is 180 degrees. This means that my third angle would be 0. This would result in there being No third angle thus it's not a triangle.
