## What are the properties of a triangle inscribed in a circle?

The properties are: 1. 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 a circle inscribed in a triangle called?**

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.

**What are the properties of incenter?**

The incenter may be equivalently defined as the point where the internal angle bisectors of the triangle cross, as the point equidistant from the triangle’s sides, as the junction point of the medial axis and innermost point of the grassfire transform of the triangle, and as the center point of the inscribed circle of …

### What is an 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 are the properties of a triangle?**

The properties of a triangle are:

- A triangle has three sides, three angles, and three vertices.
- The sum of all internal angles of a triangle is always equal to 180°. This is called the angle sum property of a triangle.
- The sum of the length of any two sides of a triangle is greater than the length of the third side.

**What is inscribed triangle?**

#### What is the radius of a circle inscribed in a triangle?

For any triangle △ABC, let s = 12 (a+b+c). Then the radius r of its inscribed circle is r=Ks=√s(s−a)(s−b)(s−c)s. Recall from geometry how to bisect an angle: use a compass centered at the vertex to draw an arc that intersects the sides of the angle at two points.

**What are properties of the incenter of a triangle?**

Definition of Incenter The incenter of a triangle is the point of intersection of all the three interior angle bisectors of the triangle. This point is equidistant from the sides of a triangle, as the central axis’s junction point is the center point of the triangle’s inscribed circle.

**What is an inscribed circle in geometry?**

Incircle. The largest possible circle that can be drawn interior to a plane figure. For a polygon, a circle is not actually inscribed unless each side of the polygon is tangent to the circle. Note: All triangles have inscribed circles, and so do all regular polygons.

## What can be inscribed in a circle?

Every circle has an inscribed regular polygon of n sides, for any n≥3, and every regular polygon can be inscribed in some circle (called its circumcircle). Every regular polygon has an inscribed circle (called its incircle), and every circle can be inscribed in some regular polygon of n sides, for any n≥3.
