If a triangle is drawn in a circle with a diameter as the base of the triangle, then the angle opposite that diameter is a right angle.
This is an extension of the theorem that the angle which an arc of a circle subtends at the centre of a circle is twice the angle which the arc subtends at the circumference.
In the case of a diameter, then the angle subtended at the centre is 180° and thus the angle at the circumference is 90°.
It is 90 degrees between the circle's diameter and its tangent
Sometimes
The length (circumference) of the curved part of a semi-circle is pi times the radius (pi*R). If the diameter is given, then the semi-circle length is 1/2 (pi * x D) because the radius is 1/2 of the diameter.(There are 2pi radians in a full circle.)A closed shape formed from a semi-circle has a perimeter P = D + (pi * D / 2)(diameter plus the curved part)
Yes and the angles around the point of intersection add up to 360 degrees.
When you horizontally cut a cylinder, you will see a circle as the resulting 2D shape. This circle is formed by the intersection of the plane (the cut) with the curved surface of the cylinder. The circle will have the same diameter as the base of the cylinder.
yes. the leg of the triangle has to be formed different because of the circle
It is the diameter of the circle formed by the three electrodes. Popular abbreviation is PCD. In a round furnace three electrodes(Normally AC furnace) are centered at the peak of the equilateral triangle. When a circle is drawn from the center covering three apexes(of triangle), such circle is called the PCD of Electrodes.vipin@vaibhavfurnaces.com
Not unless the chords are both diameters.
It is 90 degrees between the circle's diameter and its tangent

In a circle, a chord is a line segment that connects two points on the circle's circumference. A triangle can be formed within a circle using the chord as one of its sides.
Sometimes
In geometry, a 7-chord is a line segment that connects two points on a circle and divides the circle into two parts. A triangle can be formed by connecting the endpoints of a 7-chord with the center of the circle. The relationship between a triangle and a 7-chord is that the 7-chord is a side of the triangle when the center of the circle is one of the triangle's vertices.
The different types of chords that can be formed in a major scale are major chords, minor chords, diminished chords, and augmented chords.
A right-angled (90 degrees) cross (+) is formed by the two diameter lines crossing in the centre of the circle.
