ADDITIONAL COMPONENTS INCLUDED:

(1) Links to Instructional Videos: Links to videos of each lesson in the unit are included. Videos were created by fellow teachers for their students using the guided notes and shared in March 2020 when schools closed with no notice. Please watch through first before sharing with your students. Many teachers still use these in emergency substitute situations. (2) Editable Assessments: Editable versions of each quiz and the unit test are included. PowerPoint is required to edit these files. Individual problems can be changed to create multiple versions of the assessment. The layout of the assessment itself is not editable. If your Equation Editor is incompatible with mine (I use MathType), simply delete my equation and insert your own.

(3) Google Slides Version of the PDF: The second page of the Video links document contains a link to a Google Slides version of the PDF. Each page is set to the background in Google Slides. There are no text boxes; this is the PDF in Google Slides. I am unable to do text boxes at this time but hope this saves you a step if you wish to use it in Slides instead!

The arc measure corresponds to the measure of the central angle that it subtends. In terms of rotation and arc length, it's crucial to understand that all points along a given radius of a circle rotate through the same angle. However, points farther from the center of rotation trace a larger arc length because they have a greater radius.

The Exterior Secant Angle Theorem states: (you don't need to know the name of this) The measure of an angle formed by two secants intersecting in the exterior of a circle is one half the difference of the measures of the intercepted arcs. Let's go over the circles: Central <. vertex of < in the center. equal to the arc angle.

Def. of an arc. An unbroken part of a circle consisting of two points called the endpoints and all the points in between. Minor arc. Arc whose points are on the interior of the central angle. Measure equals central angle. 0<m<180. Major arc. Arc whose points are on the exterior of a central angle. Measure equals 360-central angle. 180<m<360.

Unit 10 homework 2: central angles, arc measures ... described as the amount of rotation between two straight line or planes and angles is measured in degree with the full circle being 360°. The central angle is the angle between two radii of the circle, where the radii are the straight lines extending from the center of the circle to the ...

Since you know that arc are twice the angle measure, that means arc RT is 42 * 2 = 84. Then, you have to find the measure of RS. Remember that arc RT and RS have to add up to 180 degrees because they form a semicircle (half of a circle). To find the measure of RS, just do 180 - 84 = 96 degrees.

an arc has a degree measure and a length; L (ab) = x°/360° (2 (pi)r) Arc Addition Postulate. mAB + mBC = mAC. Congruent Arcs and Angles Theorem. minor arcs are congruent iff their central angles are congruent. Study with Quizlet and memorize flashcards containing terms like 360° Theorem, Central Angle, Minor Arc (AB) and more.

The arc measure is the degree measure of the arc between the two points where the central angle intersects the circle. The arc length is the actual length of the arc itself, and it depends on both the radius of the circle and the degree measure of the arc. The formula is: x. For example, if a central angle of a circle has a measure of 60 ...
