Triangle and its Centre

A triangular wire frame (each side =2m) is placed in a region of time variant magnetic field dB//dt = (sqrt3) T//s . The magnetic field is perpendicular to the plane of the triangle and its centre coincides with the centre of triangle. The base of the triangle AB has a resistance 1(Omega) while the other two sides have resistance 2(Omega) each. The magnitude of potential difference between the points A and B will be

Distinguish between a triangle and its triangle region.

To construct a triangle, given its perimeter and its two base angles.

The ratio of the product of the sides of an equilateral triangle to its perimeter is equal to the ratio of the product of the sides of another equilateral triangle to its perimeter. Then the triangles are

Given the base of a triangle and the sum of its sides,prove that the locus of the centre of its incircle is an ellipse.
