WebMar 24, 2024 · Given a triangle, extend two sides in the direction opposite their common vertex. The circle tangent to these two lines and to the other side of the triangle is called an excircle, or sometimes an escribed circle.

WebThe equilateral triangle is also the only triangle that can have both rational side lengths and angles (when measured in degrees). When inscribed in a unit square, the maximal possible area of an equilateral triangle is \(2\sqrt{3}-3\), occurring when the triangle is oriented at a \(15^{\circ}\) angle and has sides of length \(\sqrt{6}-\sqrt{2}:\) WebAdd in the incircle and drop the altitudes from the incenter to the sides of the triangle. Also draw the lines , and . After this AB, AC, and BC are the bases of , and respectively. But they all have the same height (the inradius), so . Also the inradius of a incircle inscribed in a right triangle is as by drawing three inradiuses to the three ...
An excircle or escribed circle of the triangle is a circle lying outside the triangle, tangent to one of its sides and tangent to the extensions of the other two. Every triangle has three distinct excircles, each tangent to one of the triangle's sides. The center of an excircle is the intersection of the internal bisector of … See more In geometry, the incircle or inscribed circle of a triangle is the largest circle that can be contained in the triangle; it touches (is tangent to) the three sides.
