The base is one third of the perimeter, half of the base times the height is the area.

For a triangle to be acute, all the angles are less than 90o. In an equilateral triangle, each angle is the same; thus each is 180o ÷ 3 = 60o and so they are all less than 90o. Therefore a triangle can be both acute and equilateral.

Well, in an equilateral triangle, all three angles have to be equal. Plus, the sum of all the angles must be 180. Therefore, if you want to find on angle of an equilateral triangle, you would use the equation, 180/3=60

A right triangle can be an isosceles triangle, because the definition of an isosceles triangle is a triangle that has 2 sides equal to each other. A 45,45,90 degree triangle has 2 sides equal to each other, while the hypotenuse is different. It cannot be an equilateral triangle because of the formula a^2+b^2=c^2. With this formula, there is no possible way that: a, b, and c can all be equal to each other. To recap: It can be an isosceles triangle, but not an equilateral one.

No because an obtuse angle is greater than 90 degrees and a regular triangle is an equilateral triangle that has 3 equal 60 degree angles that add up to 180 degrees.

I think if it were to be a triangle that it would be six on each

Let's express the side length of an equilateral triangle, a, in term of the height h.a = (1/3)(h)(sq.root of 3)The perimeter equals to 3a. So we have:3a = 3[(1/3)(h)(sq.root of 3)] = (h)(sq.root of 3)] = 18(sq.root of 3)

An equilateral triangle means a triangle with all three sides with equal dimensions. For drawing an equilateral triangle first you will have to choose a measurement to draw the sides of the triangle. For example, lets take the side to be 4cm. When you draw the base of 4cm you will have to draw the other two sides of 4cm as well. Thus an equilateral triangle is constructed..

any equilateral triangle is also equiangular meaning all three angles in the triangle have the same measurement which is 60 degrees. this is because the sum of the angles in a triangle equals 180. Therefore the equilateral triangle is also acute meaning all three angles measure less than 90 degrees each.

It doesn't. It could be an equilateral triangle, with 4 equal intervals on each side.You're thinking of a right triangle with sides in the ratio of [3 to 4 to 5], with a sum of 12.Actually, I think it could be a triangle of anyshape. Any triangle can be inflated or deflated,keeping its shape so that all versions of it are similar, until its perimeter is 12.

Yes. Try making an obtuse triangle with equal sides. It doesn't work. All angles are equal to 60 degrees in an equilateral triangle.

A tetrahedron is a triangular based pyramid that has 4 equilateral triangle faces, 6 edges and 4 vertices.
