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°.
What else can I help you with?
What is the measure of the angle formed between a tangent and the diameter of a circle?
It is 90 degrees between the circle's diameter and its tangent
When chords intersect in a circle the vertical angles formed intercept conruent arcs always sometimes never?
Sometimes
How do you find the circumference of a semi-circle?
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)
If two chords intersect inside a circle the angles formed are called inscribed angles?
Yes and the angles around the point of intersection add up to 360 degrees.
What 2 D shape will you see in horizontally cut cylinder?
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.
When a right triangle is inscribed in a circle will one of the legs of the triangle always be the diameter of a circle?
yes. the leg of the triangle has to be formed different because of the circle
A chord of a circle that contains the cwnter of a circle?
A chord that contains the center of a circle is called a diameter. The diameter is the longest chord in the circle, and it divides the circle into two equal halves. It also passes through the center, making it unique among all other chords. Additionally, any angle inscribed in a semicircle formed by the diameter is a right angle.
What is pitch circular diameter in electric arc furnace?
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
When chords intersect in a circle are the vertical angles formed intercept congruent arcs?
Not unless the chords are both diameters.
What is the measure of the angle formed between a tangent and the diameter of a circle?
It is 90 degrees between the circle's diameter and its tangent
An inscribed angle is an angle formed by two chords that share an endpoint.?
An inscribed angle is formed by two chords in a circle that meet at a common endpoint on the circle's circumference. The vertex of the angle lies on the circle, and the sides of the angle are segments of the chords. The measure of an inscribed angle is half the measure of the arc that it intercepts. This property is a key characteristic of inscribed angles in circle geometry.
If two chords intersect inside a circle are the angles formed called inscribed angles?
yes
If two chords intersect inside a circle the angles formed are called inscribed angles.?
yes
An inscribed angle is formed by two radii?
false
What is the relationship between a triangle and a chord within a circle?
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.
An inscribed angle is an angle formed by two chords that share an endpoint and pass through the center.?
An inscribed angle is actually formed by two chords that meet at a point on the circle, not necessarily passing through the center. The vertex of the inscribed angle is on the circle, and the angle's sides are formed by the chords. The measure of an inscribed angle is half the measure of the intercepted arc. Therefore, it relates to the arc that lies in the interior of the angle.
When chords intersect in a circle the vertical angles formed intercept conruent arcs always sometimes never?
Sometimes
