module 7: circles, a nightmar- i mean, a geometric perspective by nataly aviles https://padlet.com/avilesn0036/sadsadstudent made with shaking hands bc im sO cLOSE TO GIVING UP UGHHSGHDGUGHJDFKJSMB en-us 2017-04-05 19:40:35 UTC 2025-11-27 23:05:24 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Brightnessdown.png words that make no sense avilesn0036 https://padlet.com/avilesn0036/sadsadstudent/wish/164994138 tangent: a line that intersects a circle in exactly one point
chord: a segment with endpoints on the circle
secant: a line that intersects the circle twice
inscribed arc: the portion of a circle that lies between two lines, rays, or line segments that intersect the circle

a = pi(r)^2
a of a triangle/prism = .5(bh)
a of a cylinder = pi(r)^2
a of a trapezoid = .5(b1 + b2) (h)
a of a sector = n / 360 (pi(r)^2)
v = (bh) OR pi(r)^2(h)
sa = 2pi(r)^2 + 2pi(r)(h)
central angle = 360 / n
y = sqrt 3(x) OR sqrt 2(x)
arc length = n / 360 (2pi(r))
radians to degrees = rad (180) / pi
degrees to radians = n(pi) / 180

- all radii in a circle are congruent
- the relationship between inscribed & central angles is 2
- opposite angles in inscribed quadrilaterals are supplementary
- the triangles of a prism act as its base
- when a radius & tangent line meet, they create 90 degrees
- central angles & exterior angles are 180 degrees
- all arcs in the same sector have the same value for the ratio of arc length to radius
- an arc of a circle with the same length as the radius of that circle corresponds to an angle of 1 radian
- a full circle corresponds to an angle for 2pi radians

40 =
40/2 = x
20 = x
