ABC is an equilateral triangle of side 2a. Find each of its altitude.
Each side of an equilateral triangle measures 8 cm. Then, the semiperimeter of the triangle is ……………… cm.
If the equation of the base of an equilateral triangle is x+y=2 and the vertex is (2,-1) , then find the length of the side of the triangle.
The base of an equilateral triangle with side 2a lies along the Y-axis such that the mid-point of the base is at the origin. Find vertices of the triangle.
The sides of an equilateral triangle are increasing at the rate of 2cm/sec. The rate at which the area increases, when side is 10 cm is ………..
In an equilateral triangle with side a, prove that, the area of the triangle (sqrt(3))/(4)a^(2) .
The resistance of each side of an equilateral triangle is 3 ohm. Calculate the equivalent resistance between ends of a side.
The resistance of each side of an equilateral triangle is 6 ohm. Calculate the equivalent resistance between ends of a side.
Now draw a triangle ABC and measure its sides. Find the sum of the sides AB + BC, BC + AC and AC + AB, compare it with the length of the third side. What do you observe? You will observe that AB + BC > AC, BC + AC > AB and AC + AB > BC.
Construct an equilateral triangleABC in which AB=BC=CA=4cm. Write the steps of construction.
