Show that the angles of an equilateral triangle are `60^@` each.

write the ratio of the angles of an equilateral triangle.

Let's write the ratio of the three angles of equilateral triangle.

Draw the incircle of an equilateral triangle of side 7 cm.

Show that the following points form an equilateral triangle A(a, 0), B(-a, 0), C(0, a sqrt(3))

The ratio of the areas of an equilateral triangle and a square is sqrt3:2. If the length of the diagonal of the square be 60 cm, find the perimeter of the equilateral triangle.

Three charges are placed at the vertices of an equilateral triangle of side l. Each of the charges is q. Find out the force on a charge Q placed at the center of mass of the triangle.

Prove that the area of the equilateral triangle described on the side of a square is half the area of the equilateral triangles described on its diagonal.

If the length of the sides of an equilateral triangle be increased by 1 cm each, then the area of the triangle increases by sqrt(3) sq-cm. Find the length of the equilateral triangle.

Draw an equilateral triangle whose sides are 5.2 cm. each
