An Equilateral Triangle Abc Is Inscribed In A Circle Of Radius 12 C An equilateral triangle abc of side 24 cm is inscribed in a circle which is centered at o, as shown below. then the radius of this circle isa. 8 √3 cmb. 6 √3 cmc. 4 √3 cmd. 2 √3 cm. In fig 4, a circle is inscribed in an equilateral triangle abc of side 12 cm. find the radius of inscribed circle and the area of the shaded region.[use π=3.14 and √3=1.73].
Equilateral Triangle Geometry An equilateral triangle of side = 12 cm. area of the equilateral triangle = √3 4(side) 2 = √3 4(12) 2 = 36√3 cm 2. perimeter of triangle abc = 3 x 12 = 36 cm. so, the radius of incircle = area of triangle 1 2 (perimeter of triangle) = 36√3 1 2 x 36 = 2√3 cm. therefore, area of the shaded part = area of equilateral triangle – area. H = a × √3 2. substituting h into the first area formula, we obtain the equation for the equilateral triangle area: area = a² × √3 4. 2. using trigonometry. let's start with the trigonometric triangle area formula: area = (1 2) × a × b × sin(γ), where γ is the angle between the sides. we remember that all sides and all angles. In the given figure, a circle is inscribed in an equilateral triangle abc of side 12 cm. find the radius of the inscribed circle and the area of the shaded region. [use √ 3 = 1.73 a n d π = 3.14 ]. An equilateral triangle is a special case of a triangle where all 3 sides have equal length and all 3 angles are equal to 60 degrees. the altitude shown h is hb or, the altitude of b. for equilateral triangles h = ha = hb = hc. if you have any 1 known you can find the other 4 unknowns.

An equilateral triangle is a special case of a triangle where all 3 sides have equal length and all 3 angles are equal to 60 degrees. the altitude shown h is hb or, the altitude of b. for equilateral triangles h = ha = hb = hc. if you have any 1 known you can find the other 4 unknowns. Because the equilateral triangle is, in some sense, the simplest polygon, many typically important properties are easily calculable. for instance, for an equilateral triangle with side length \(\color{red}{s}\), we have the following: the altitude, median, angle bisector, and perpendicular bisector for each side are all the same single line. An equilateral triangle is also called an equiangular triangle since its three angles are equal to 60°. in an isosceles triangle, the base angles are congruent. recall from above that an equilateral triangle is also an isosceles triangle. since de≅ef, the base angles, ∠d and ∠f, are congruent. also, since de≅df, ∠e≅∠f, so by the.
