360 - 75 = 285
It is the subtended angle of the arc
An angle subtended at the semicircular arc is 90 degrees.
It will be the same angle subtended by its circumference.
May things, but the probable answer sought here is a diameter of a circle, at the circumference of the circle.
Yes. It follows from one of the circle theorems which states that the angle subtended in a semicircle is a right angle.
A circle subtends 360° . Therefore. if the angle subtended at the centre of a circle by an arc is greater than 180° then this is the major arc. By comparison, the minor arc will subtend an angle less than 180°
It is the subtended angle of the arc
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
An angle subtended at the semicircular arc is 90 degrees.
It will be the same angle subtended by its circumference.
Yes, there can be congruent arcs on a circle. Arcs which subtend the same angle at the center are considered as congruent.
It is the consequence of one of the circle theorems and in some books, it is considered a theorem itself. The underlying proposition is that the angle subtended at the circumference of the circle by any arc of a circle is half the angle subtended at the centre. In the case of a semicircle, the arc is the half circle and the angle at the centre is the one that the diameter makes at the centre of the circle ie 180 degrees. So the angle at the circumference is half that ie 90 degrees.
May things, but the probable answer sought here is a diameter of a circle, at the circumference of the circle.
Yes. It follows from one of the circle theorems which states that the angle subtended in a semicircle is a right angle.
an angle subtended by an arc is double at the center
A central angle has its vertex at the center of a circle, and two radii form the Arms. Central angle AOC is described as subtended by the chords AC and by the arc AC. An inscribed angle has its vertex on the circle, and two chords form the arms. Inscribed angle ABC is also described as subtended by the chord AC and by the arc AC.
Let us recall the formula for the circumference of a circle. That one is 2pi r. r is the radius of the circle and 2pi is the angle in radian measure subtended by the entire circle at the centre. If this is so, then any arc length 'l' will be equal to the product of the angle in radian measure subtended by the arc at the centre and the radius.So l = theta r. Say theta is the angle subtended by the arc at the centre.Therefrom, r = l / Theta.
