For a triangle △ABC, let s = 12 (a+b+ c). Then the radius R of its circumscribed circle isR=abc4√s(s−a)(s−b)(s−c). In addition to a circumscribed circle, every triangle has an inscribed circle, i.e. a circle to which the sides of the triangle are tangent, as in...
The product of the inradius and semiperimeter (half the perimeter) of a triangle is none other than the area! This fact is not hard to derive, once you break up the triangle's area in the right way.Explanations (3) Jonathan Heller Text 7 Finding Area with the Inradius Vocabulary There...
there angle bisectors meet(the incenter).Construct the angle bisectors of A and B .They intersect at the incenter(I).The incircle is also tangent to all sides of triangle so construct the perpendicular from the incenter to AB.Using IZ as the radius,the incircle can be constructed.....
aIn words, we have found that the area of a triangle is the product of the radius of its inscribed circle by its semi-perimeter. 在词,我们发现三角的区域是半径的产品它题写的圈子由它的半周长。[translate]
Calculating this gives a specific value that can be simplified. ConclusionBased on the calculations:1. The area of triangle ABC is 50 (Correct).2. The distance between orthocenter and circumcenter is 5 (Correct).3. The sum of circumradius and inradius does not equal 10 (Incorrect).4. The...

In an isosceles triangle A B C , if A B=A C=13 cm and the altitude from A on B C is 5 cm, find B C .
The incircle of a triangle is the largest circle contained in the triangle, it is tangent to the three sides. The center of the incircle is called the triangle's incenter and the radius of the incircle is called inradius, which is denotedr. ...
