You have points A, B, and C. Using a compass and straight edge, find a perpendicular bisector of AB (that is, a line that is perpendicular to AB and intersects AB at the midpoint of AB. Next, find a perpendicular bisector of BC. The two lines you found will meet at the center of the circle.
What else can I help you with?
How would you explain how to find sine and cosine within each quadrant of a unit circle?
To find the sin/cos at a given point on the unit circle, draw a radius to that point. Then break the radius into components - one completely horizontal and one completely vertical. The sine is the vertical component, the cosine is the horizontal component.
How do you find a slope of a line?
That depends upon what you are given - the equation of the line, the coordinates of 2 points on the line, etc.
How do you find angle on triangle?
Given only the information provided in the question, the answer is to measure it.
How does geometric properties help you find the value of trigonometric functions?
Geometric properties, particularly those related to right triangles and the unit circle, provide a visual framework for understanding trigonometric functions. In a right triangle, the ratios of the lengths of the sides (opposite, adjacent, and hypotenuse) directly define sine, cosine, and tangent. Similarly, on the unit circle, the coordinates of points correspond to the values of these functions for different angles, allowing for easy calculation of sine and cosine values. Thus, geometric insights simplify the evaluation and interpretation of trigonometric functions.
What can you solve in the Pythagorean theorem?
Given the lengths of two sides of a right triangle, you can find the length of the other side.
How do you find the center of a circle with two given points?
If you're only given two points, and you're told that they both lie on a circle,then there are an infinite number of possible circles, and therefore an infinitenumber of possible centers. In order to pin it down, you need three points.
How do you find the center or midpoint of a circle given one endpoint of the diameter?
to be honest I dont know
What is a center coordinate of 2 points known circle?
Knowing two points on a circle does not define a unique circle, so it is impossible to find the centre of the circle as there are infinitely many centres possible.
How to find the radius of a circle?
divide the diameter(the length of a straight line passing through the center of a circle and connecting two points on the circumference)by 2
What is the answer A circle of center (-3 -2) passes through the points (0 -6) and (A 0). Find A.?
The value of A works out as -7.582575695 because both points will have an equal distance of 5 units from the center of the circle (-3, -2)
How to find the center of a circle in woodworking?
To find the center of a circle in woodworking, draw two diagonal lines from opposite corners of the circle. Where the lines intersect is the center of the circle.
Does a circle have an area?
A circle *encloses* an area, and the "area of a circle" is the area it encloses, πr^2. A circle is a 1-dimensional curved line; it is a set of points equidistant from a given point (the center), with that distance being the radius of the circle. This means the inside of the circle is not part of the circle (it's called a disk if you include the inside points).To find the area, multiply pi (π) by the radius squared (r^2), so you get πr^2.Yes, it does.
How do you work out the radius of a circle without knowing the area?
This depends on what information you are given.If you have the circumference of the circle, you know that:c = 2πr∴ r = c / 2πIf you have the diameter of the circle, it's radius is half of that:r = d/2If you are given any three points on the circle's perimeter, you can use those to find the radius. This can be done with the following steps:Take any two of those three points, and find both their halfway point and the slope of the line on which they lie.With those, work out the equation for a line that passes through that halfway point, and is perpendicular to the line on which those points lie.Repeat those two steps with any other two of the three points .With the two lines you now have, find their point of intersection. That will be the center of the circle.Now find the distance from that center point, to any one of your three given points. That is the circle's radius.Also, if you have an equation for the circle, then you can work it out that way. The equation would need to be rearranged into the format (x - a)2 + (y - b)2 = r2. The last variable, "r", is your radius.
How do you find radius of a circle?
Draw a line from any part on the outside of a circle to the exact center of the circle. * * * * * That is fine if you know where the center is but not much use if you are just given a circle and do not know where the exact centre is. In this case: Draw a chord - a straight line joining any two points on the circumference of the circle. Then draw the perpendicular bisector of the chord. Draw another chord and its perpendicular bisector. The two perpendicular bisectors will meet at the centre.
What is centripetal acceleration and find its magnitude and direction in the case of uniform circular motion?
Centripetal acceleration is the acceleration that points towards the center of a circular path. Its magnitude is given by a = v^2 / r, where v is the speed of the object and r is the radius of the circle. The direction of centripetal acceleration is towards the center of the circular path.
How to find the center of a circle for drilling?
To find the center of a circle for drilling, you can use a compass to draw two intersecting lines across the circle. The point where the lines meet is the center of the circle. You can then mark this point for drilling.
How many circles can pass through two given points?
Two points determine a unique line. Therefore, there are infinitely many circles that can pass through two given points. This is because a circle can be defined by its center, which can lie anywhere along the perpendicular bisector of the line segment connecting the two points.
