New cards

Tangent and Intersecting Chord formula

m∠ = 1/2 measure of corresponding arc

<p>m∠ = 1/2 measure of corresponding arc</p>
2
New cards

2 chords intersecting inside a circle formula

m∠ = 1/2 (corresponding arc + vertical angles corresponding arc

<p>m∠ = 1/2 (corresponding arc + vertical angles corresponding arc</p>
3
New cards

Angles outside of a circle formula (for 3 types)

m∠ = 1/2 (further arc - closer arc) (can also be formatted as bigger arc - smaller arc)

<p>m∠ = 1/2 (further arc - closer arc) (can also be formatted as bigger arc - smaller arc)</p>
4
New cards

Circumscribed ∠'s an angle formed by 2 tangents formula

m∠ = 180 - opposite central angle

<p>m∠ = 180 - opposite central angle</p>
5
New cards

2 chords intersecting inside a circle (length) formula

Half of segment 1 ⋅ other half of segment 1 = Half of segment 2 ⋅ other half of segment 2

<p>Half of segment 1 ⋅ other half of segment 1 = Half of segment 2 ⋅ other half of segment 2</p>
6
New cards

Secant lengths that intersect in a circle formula

outside piece of secant ⋅ whole piece = other outside piece ⋅ whole piece of the other

<p>outside piece of secant ⋅ whole piece = other outside piece ⋅ whole piece of the other</p>
7
New cards

Finding length with secant and length formula

half of segment ⋅ other half of segment = tangent²

<p>half of segment ⋅ other half of segment = tangent²</p>
8
New cards

equation of a circle

(x-h)²+(y-k)²=r², (h, k) is the center, r is the radius.

<p>(x-h)²+(y-k)²=r², (h, k) is the center, r is the radius.</p>
9
New cards

Circumference of a circle

2πr or πd

<p>2πr or πd</p>
10
New cards

Arc Length Formula

aL = arc measure/360 ⋅ circumference

<p>aL = arc measure/360 ⋅ circumference</p>
11
New cards

Radian

360° = 2π radians

12
New cards

Converting Degrees into Radians

π/180

<p>π/180</p>
13
New cards

converting radians into degrees

180/π

<p>180/π</p>
14
New cards

Area of a circle formula

A=πr²

<p>A=πr²</p>
15
New cards

Area of a sector

arc measure/360 ⋅ πr²

<p>arc measure/360 ⋅ πr²</p>
