Three congruent angles means it is an equilateral triangle, so by definition it has 3 congruent sides. Or, by the Sine Rule of triangles

a/sinA = b/sinB = c/sinC

and since A = B = C (given) then a = b = c.

.

a/sinA = b/sinB = c/sinC

and since A = B = C (given) then a = b = c.

The third angle is also 60 degrees, thus it's an equilateral triangle.

A contradiction is what. An equilateral triangle has 3 equal sides, and therefore equal angles. An isosceles triangle has 2 equal sides and one shorter or longer..

Given your limited description, PQ can be any length (though equal to QR) and the point R can be anywhere in the coordinate space. Would you care to provide some additional details? Perhaps a diagram?

Well, there is classification by sides, **equilateral** with 3 equal sides, **Isosceles** with two equal sides, and **scalene** with no equal sides, but you talk about angles, but I wanted to point out equilaterals have 3 equal angles, isoceles have 2 equal angles and scalene have no equal angles.

So, now we talk about angles: a**Right** trianlge has one angle that is 90 degrees, an **Obtuse** triangle has one angle greater than 90 degrees, and an **Acute** has no angles over 90 degrees.

Thus, it is possible to have a (scalene or isoceles) AND (acute, obtuse, or right) triangle, but never an equilateral AND (obtuse or right). The angles can't be equal and 90+ degrees if all three must equal 180 degrees.

Well, just multiply 7.5 by 3. Solution: 22.5

Assuming you are specifying Area = sqrt(243/4) =
7.79422
Then the sides of the equilateral triangle are: 4.24264

Let ABC be the equilateral triangle,

and PC be the line joining the mid point of A and C.

We know that equilateral triangle has equal angles which means

Now,

in triangle AHC

Sin(THETA) = AH/AC

That is...

Sin(60) = (7root3)/AC

or AC = (7root3)/Sin(60)

AC=14

Perimeter of equilateral triangle ABC = 3 x Side

= 3 x 14

= 42

and PC be the line joining the mid point of A and C.

how big is the triangle? if the coins are a mile in diameter doesnt mean you cant have an equilateral triangle with legs of 32 miles long.

or are you asking for the equation?

i will send you on the path to the equation.

if you draw a circle on a piece of paper then draw a triangle around it where is the center? if the triangle were a perfect equilateral then the circle would be a perfect circle touching the sides of the triangle.

its important to know where the center is because the center of the circle to the edge of the circle is the radius.

so the center of a triangle is the center of the circle. therfeore the radius of the circle will equal hieght/2...

thinking that way you can say that if there were three coins then the center of the triangle cant be occupied by a coin but is very close to an edge. where is the center of the coin?
