Approach: Formula for calculating the inradius of a right angled triangle can be given as r = ( P + B – H ) / 2. And we know that the area of a circle is PI
The area of incircle of an equilateral triangle is 154\ c m^2 . The perimeter of the triangle is (a) 71.5 cm (b) 71.7 cm (c) 72.3 cm (d) 72.7 cm
Show that ΔDEF is also an equilateral triangle. View Solution AL, BM and CN are perpendicular from angular points of a triangle ABC on the opposite sides BC, CA and AB respectively. Δ is the area of triangle ABC, (r ) and R are the inradius and circumradius. If perimeters of ...
Radii of in-circle and ex-circles of a right- angled triangle In this article, I provide a relation connecting the lengths of the tangents from the vertices of a right-angled triangle to its incircle and ex-circles, in terms of its inradius and ex-radii. I give a geometric proof as...
