General Circles
(x-h)2 + (y-k)2 = r2
What is the equation of a circle?
A line that goes from one side of a circle to the other side of a circle.
What is a Chord?
The angle formed by joining the endpoints of an arc to the center of the circle.
What is a central angle?
The number of tangents to a circle you can possibly draw from a single point outside the circle.
What is two?
A line that passes through a circle at exactly 2 points.
What is a secant?
The radius does this to a chord when they are perpendicular.
What is bisect?
The angle formed by joining the endpoints of an arc to a point on the circle.
What is an Inscribed Angle?
A circle has radius 5 and a central angle of 68 degrees. This is the arc length.
What is 17pi / 9?
The longest chord in a circle.
What is a Diameter?
The type of angle made by a radius intersecting a tangent at the point of tangency.
What is a right angle?
The angle formed by two intersecting chords inside a circle.
What is 1/2 the sum of the intercepted arcs?
These types of angles are equal when they intercept the same arc.
What are Inscribed Angles?
A circle has radius 2 and central angle 54 degrees. This is the sector area.
What is 3pi / 5 cm?
The angle inscribed in a semicircle.
What is a right angle?
Four tangents to a circle make this figure when they are ninety degrees to teach other.
What is a square?
How to find the segments of two intersecting chords.
What is (piece1)(piece2)=(piece1)(piece2)?
This angle is twice the inscribed angle when they intercept the same arc.
What is a Central Angle?
A 10 inch pie is cut into 8 slices. Your family eats 3 slices. This is the amount of pie that is left.
What is 75pi / 8?
The process for writing the equation of a circle in standard form.
What is completing the square?
In a triangle, the line that connects the tangent and the radius of a circle.
What is a hypotenuse?
If you were to draw two different chords and bisect them, the two bisectors would intersect at this point.
What is the center (origin) of the circle?
How to find an angle that is outside of the circle.
What is 1/2 the difference between the intercepted arcs.
A dream catcher with diameter 11 cm is strung with a web of straight chords. What is the length of the longest chord?
What is 22 cm?
