The area of an equilateral triangle is s 2 3 4 \frac{s^2\sqrt{3}}{4} 4 s 2 3 . ∴ Height / 3 = in radius ∴ Height = Median = 3*3 = 9 cm Find the radius of the inscribed circle of this triangle… Then the length of each of its medians is : [A]4 cm [B]9 cm [C]9.5 cm [D]12 cm Show Answer 9 cm In the equilateral triangle centroid, incentre, orthocentre, coincide at the same point. An isosceles triangle has two 10.0-inch sides and a 2w-inch side. https://www.khanacademy.org/.../angle-bisectors/v/inradius-perimeter-and-area geometry. You can then use the formula K = rs to find the inradius r of the triangle. Computed angles, perimeter, medians, heights, centroid, inradius and other properties of this triangle. R = √51975 35 = 3√231 7. A = B = C = 3 π r : R : r 1 = 4 R sin 2 A sin 2 B sin 2 C : R : 4 R sin 2 A cos 2 B cos 2 C Given triangle is an equilateral triangle. The in-radius of an equilateral triangle is of length 3 cm. The derivation is easy. an equilateral triangle of side 20cm is inscribed in a circle calculate the distance of a side of the triangle from the centre of the circle . The in-radius of an equilateral traingle is of length 3 cm. 5 5 5 - Equilateral triangle, area=10.83. ∴ Height 3 = in radius ∴ Height = Median .. 7). If the sides of the triangles are 10 cm, 8 cm and 6 cm find the radii of the circles. With the vertices of the triangle ABC as centres, three circles are described, each touching the other two externally. The Euler line degenerates into a single point. Its radius, the inradius (usually denoted by r) is given by r = K/s, where K is the area of the triangle and s is the semiperimeter (a+b+c)/2 (a, b and c being the sides). The orthocenter, circumcenter, incenter, centroid and nine-point center are all the same point. Two circles are placed in an equilateral triangle as shown in the figure. By Heron's Formula the area of a triangle with sidelengths a, b, c is K = √s(s − a)(s − b)(s − c), where s = 1 2(a + b + c) is the semi-perimeter. Then the length of each of its medians is 5 In-radius of equilateral triangle of side a = a/ 2 √ 3 Diameter of larger circle = a/ 2 √ 3 Let us say common tangent PQ touches the two circle at R, center of smaller circle is I. Geometry In-radius of equilateral triangle of side a = a 2 3 Diameter of larger circle = a 2 3 Let us say common tangent PQ touches the two circle at R, center of smaller circle is I. The circumradius of an equilateral triangle is s 3 3 \frac{s\sqrt{3}}{3} 3 s 3 . You can then use the formula K = r s to find the inradius r of the triangle. The in-radius of an equilateral triangle is of length 3 cm. The radius of a regular polygon is the radius of the circumscribing circle. then the length of each of its medians is 2 See answers AryanTennyson AryanTennyson In the equilateral triangle centroid, incentre, orthocentre, coincide at the same point.
