Hence the radius of the inscribed circle is3. Here a and b are the sides and c is the hypotenuse of the right angled triangle. This is used when the circle is inscribed in a right angled triangle. How do you find the incircle of a triangle? Constructing Incircle of a Triangle - Ste...
The formula for the radius of the circle circumscribed about a triangle (circumcircle) is given by $R = \dfrac{abc}{4A_t}$ where At is the area of the inscribed triangle. Derivation: If you have some questions about the angle θ shown in the figure above, see the relationship between ...
Inradius: Radius of the incircle These are all the terms we need to know to use this method of finding area. Finding the Inradius We can start with a triangle ABC. We're going to draw a bisector from each angle. This is a line that splits the angle in half. The point where they...
Step by step video & image solution for One angle of an isosceles triangle is 120^0 and the radius of its incricel is sqrt(3)dot Then the area of the triangle in sq. units is 7+12sqrt(3) (b) 12-7sqrt(3) 12+7sqrt(3) (d) 4pi by Maths experts to help you in doubts & sc...
