How do you find the area of a triangle inside an inner circle?
The area of a circle inscribed inside an equilateral triangle is found using the mathematical formula πa2/12. Lets see how this formula is derived, Formula to find the radius of theinscribed circle
In geometry, the incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides. The center of the incircle is a triangle center called the triangle's incenter.

When a triangle is inscribed in a circle?
Inscribed Circles of TrianglesThe inscribed circle will touch each of the three sides of the triangle in exactly one point. The center of the circle inscribed in a triangle is the incenter of the triangle, the point where the angle bisectors of the triangle meet.
What is the measure of a triangle in a circle?
The angle in this triangle at the center of the circle has measure 360o/3 = 120o. The sum of the angles in any triangle is 180o hence each of the other angles in this triangle has measure (180o - 120o) = 30o.When an equilateral triangle is inscribed in a circle?
For an equilateral triangle all sides are equal and angle is equal to 60°. To find the area of an equilateral triangle inscribed in a circle, we have to find the length of the side of the equilateral triangle. Therefore, the area of an inscribed equilateral triangle is 27√3 cm2.What kind of triangle is inscribed in a semicircle?
(see figure on right). No matter where the point is, the triangle formed is always a right triangle.Area of inscribed equilateral triangle (some basic trig used) | Circles | Geometry | Khan Academy
Is a triangle inscribed in a semicircle a right triangle?
Since a triangle inscribed in a semicircle is always a right triangle, triangle ABC is a right triangle. Therefore, AC is both the hypotenuse of triangle ABC and the diameter of the semicircle.How do you find a right triangle in a circle?
If a right triangle is inscribed in a circle, then its hypotenuse is a diameter of the circle. 2. If one side of a triangle inscribed in a circle is a diameter of the circle, then the triangle is a right triangle and the angle opposite the diameter is the right angle.What is the area of largest triangle that is inscribed in a semicircle?
Therefore, the area of a largest triangle that can be inscribed in a semicircle of radius r is r² square units.What is the measure of an angle inscribed in a semi circle?
If an angle is inscribed in a semicircle, it will be half the measure of a semicircle (180 degrees), therefore measuring 90 degrees.What is a inscribed triangle?
An inscribed triangle is a triangle inside a circle. To draw an inscribed triangle, you first draw your triangle. Then you draw perpendicular bisectors for each side of the triangle. Where they meet is the center of your circle.What is the area of an equilateral triangle inscribed in a circle of unit radius?
So, r = {x / (√3)}. Here, r = 5 cm. So, x = (5√3) cm. Area of an equilateral triangle = [{(√3) / 4} * (x^2)] = [{(√3) / 4} * 75] sq cm ≈ 32.475 sq cm.How do you find the height of an equilateral triangle inscribed in a circle?
- In an equilateral triangle the center of the circle in which it is inscribed divides the altitude in the ratio 2:1 which is a property.
- hence 2x+1x=altitude.
- altitude =3x.
- of which the 2x portion is the radius hence 2x=3.
- which implies x=1.5units.
- so altitude is 3*x=3*1.5=4.5units.
- hence the answer is 4.5 Units.
What is the radius of Incircle of equilateral triangle?
Inscribed circle of an equilateral triangle is made through the midpoint of the edges of an equilateral triangle. is the length of the side of equilateral triangle. , where r is the radius of given circle. Also the radius of Incircle of an equilateral triangle = (side of the equilateral triangle)/ 3.What is the area of the shaded part?
The area of the shaded region is the difference between the area of the entire polygon and the area of the unshaded part inside the polygon. The area of the shaded part can occur in two ways in polygons. The shaded region can be located at the center of a polygon or the sides of the polygon.
