When constructing an equilateral triangle what step comes after six arcs are created on the circle?
When constructing an equilateral triangle, what step comes after six arcs are created on the circle? Connect every other intersection of an arc and the circle with a segment.
How many equilateral triangles are there in a circle?
A Circle is evenly divided into six equal triangles.
When circumscribing a equilateral triangle about a circle The first step is to draw its?
Constructing a Circumscribed Triangle In the first step, just like before, you draw your triangle. In the second step, instead of drawing your perpendicular bisectors, you'll now draw your angle bisectors. Your angle bisector is the line that cuts your angle in half. You'll draw one for each angle.
How do you find the sides of an equilateral triangle inscribed in a circle?
Hint: Draw the figure. The line connecting the centre of the circle to the vertex of the triangle is taken as radius. Draw perpendicular to the base of the triangle. Solve the triangle using Pythagoras theorem and find the length of the side.

How do you find the sides of a equilateral triangle inscribed in a circle?
Hint: Draw the figure. The line connecting the centre of the circle to the vertex of the triangle is taken as radius. Draw perpendicular to the base of the triangle. Solve the triangle using Pythagoras theorem and find the length of the side.
How many triangles can be inscribed in a circle?
Every circle has an inscribed triangle with any three given angle measures (summing of course to 180°), and every triangle can be inscribed in some circle (which is called its circumscribed circle or circumcircle). Every triangle has an inscribed circle, called the incircle.
When constructing an equilateral triangle by hand which step comes after constructing a circle?
When constructing an equilateral triangle by hand, which step comes after constructing a circle? Set compass to the radius of the circle.
How do you find the area of an equilateral triangle circumscribed in a circle?
We know that area of circle = π*r2, where r is the radius of given circle. We also know that radius of Circumcircle of an equilateral triangle = (side of the equilateral triangle)/ √3. Therefore, area = π*r2 = π*a2/3.
How many equilateral triangles are in a circle?
A Circle is evenly divided into six equal triangles.

How many circles fit in a triangle?
Every triangle has three distinct excircles, each tangent to one of the triangle's sides. . Because the internal bisector of an angle is perpendicular to its external bisector, it follows that the center of the incircle together with the three excircle centers form an orthocentric system.

How do you construct an equilateral triangle with side 4 cm?
Steps of construction:
- Draw a line segment BC = 4 cm.
- Taking B as a centre and radius 4 cm, draw an arc above BC.
- With same radius and centre C, draw an arc which cut the previous arc at A.
- Join AB and AC.
- Hence ABC is the required triangle.

How many arcs are drawn to construct a 90-degree angle?
two arcs With D as a center and with the same radius draw another arc and name it as E. With the same radius and with D and E as center draw two arcs that cut each other and label it as F. Now join the lines F and A. Now we can observe that angle FAB = 90°.
How do you construct an equilateral triangle in Class 9?
Steps of construction :
- Draw a line segment AB of length 5.5 cm.
- Taking 5.5 cm as radius, and A as centre, draw an arc.
- Taking 5.5 cm as radius, and B as centre, draw another arc.
- Let C be the point where the two arcs intersect . Join AC and BC and label the sides.
What is the triangle inscribed in a circle?
When a circle inscribes a triangle, the triangle is outside of the circle and the circle touches the sides of the triangle at one point on each side. The sides of the triangle are tangent to the circle. draw in the angle bisectors. The intersection of the angle bisectors is the center of the inscribed circle.
How many triangles can be formed from 4 points on a circle?
10. Hint: We first establish the fact that the no three points out of those four points in the circle is collinear.

Does an equilateral triangle fit in a circle?
This is the largest equilateral triangle that will fit in the circle, with each vertex touching the circle….Proof.
| Argument | Reason | |
|---|---|---|
| 3 | OAB is an equilateral triangle | AB was drawn with compass width set to OA, and OA = OB (both radii of the circle). |
| 4 | m∠AOB = 60° | All interior angles of an equilateral triangle are 60°. |
How many angles are in a circle?
An angle of a circle is an angle that is formed between the radii, chords, or tangents of a circle. We saw different types of angles in the “Angles” section, but in the case of a circle, there, basically, are four types of angles. These are central, inscribed, interior, and exterior angles.
How do you find the length of an arc in a circle?
The arc length of a circle can be calculated with the radius and central angle using the arc length formula,
- Length of an Arc = θ × r, where θ is in radian.
- Length of an Arc = θ × (π/180) × r, where θ is in degree.
How many circles does an equilateral triangle have?
In the figure there are infinitely many circles approaching the vertices of an equilateral triangle, each circle touching the other circles and sides of the triangle. If the triangle has sides of length 1, find the total area occupied by the circles.
