- 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 called the triangle's incenter.
- The center of the incircle can be found as the intersection of the three internal angle bisectors.
- You draw three lines. Each line from one triangle head point to the opposite triangle side and bisecting the angle. These three lines will intersect in one point which is the circle center.

What are the sides of an angle inscribed into a circle?
They are straight lines, part s of which form chords of the circle.
A circle is inscribed in an equilateral triangle of side 6 find area of square inscribed in a circle?
The answer in 6.... draw an angular bisector from one of the angles to the centre of circle then draw a perpendicular from the centre of circle. Those to lines will form a triangle... use trigonometry and find the length of the perpendicular, which is also a radius... double the radius and u will get the diagonal for the square... using formula :- (Side)^2 + (Side)^2 = (Diagonal)^2, find the side of square and square the answer, which will give you your final answer
What is a shape that does not have parrelell lines?
a circle or a triangle
Which shape could never have perpendicular lines a circle a triangle a rectangle or a square?
A circle !!!!!!
How do you get the center of a triangle?
Bisect two of the angles. The intersection of the resulting lines is the triangle's centre.

Circle fits in a triangle and makes tangent with three sides of triangle if one corner of triangle is 30 degrees what is arc of contact of circle for that triangle corner?
This problem can only be solved in terms of the radius or the diameter of the inscribed circle.Arc length = 5.pi.d/12 = 10.pi.r/12 = (0.833333)pi.r.This can be solved by realizing that the triangle is inherently isosceles. One must also assume that there is only one 30o angle in the triangle, meaning the peak angle of the isosceles triangle is 30o. Imagine then that there are two radial lines extending from the center of the circle to each of the two tangent points of the equal sides of the triangle. The angle between these lines can be seen to be 150o. Therefore, the arc contained between these lines is 150/360 of the circle. Since circumference is equal to pi.d, the above equation can be derived.

How many lines of symmatry in a circle?
A circle has an infinite number of lines of symmetry. Any chord of the circle that passes through its center will be line of symmetry. And there are an infinite number of lines that can be drawn through the center of the circle.
Which shape could never have perpendicular lines a circle a triangle a rectangle or a square?
A circle !!!!!!
Which solid figure does not have a face that is a triangle?
A circle * * * * * On the right lines but a circle is not a solid figure. How about a sphere?
How many lines of symmetry does a circle have?
A circle has an infinite number of lines of symmetry. Any chord of the circle that passes through its center will be a line of symmetry. And there are an infinite number of lines that can be drawn through the center of the circle, the length of which is equal to the diameter of the circle.

How many lines on symmatrie does a circle have?
A circle has an infinite number of lines of symmetry. The circle is symmetricalacross any line that passes through its center.
How many lines of symmetry are there in a circle?
A circle has infinite lines of symmetry, any line going through the center is a line for symmetry.

i dont you figure it out
