Q4, HW #11 - Quizizz - Unit 12 Review 2.0

Match the vocabulary:

• secant line

• a chord that goes through the center

• diameter

• a segment that starts at the center and touches the circle once

• radius

• a segment that touches the circle twice

• chord

• a line that touches the circle one time

• tangent line

• a line that goes through circle twice

match the vocabulary:

• semicircle

• part of the circumference (in ft, in, m, etc...)

• major arc

• the degrees of the arc

• arc length

• an arc with MEASURE equal to 180°, use 3 letters to name

• minor arc

• an arc with MEASURE less than 180°, use 2 letters to name

• arc measure

• an arc with MEASURE more than 180°, use 3 letters to name

match the vocabulary:

• angle outside circle

• 
• angle formed by tangent and chord

• 
• central angle

• 
• inscribed angle

• 
• angle inside circle, not central

• 

match the vocabulary:

• point on a circle

• (x, y)

• point of tangency

• the point where the tangent line touches the circle

• tangent segment

• (h, k)...the point all the points in the circle are equidistant to

• circle

• part of the tangent line

• center

• the set of all points in a plane equidistant to a central point

match the vocabulary:

• sector of circle

• 
• segment of circle

• 
• arc measure

• 
• area of circle

• 
• arc length

• 

match the formula

• inscribed angle in a semicircle

• 
• area of circle

• 90°

• inscribed angle

• 
• circumference

• = 1/2 arc measure

• central angle

• = arc measure

match the ways to solve for these angles:

• angle = 1/2 arc measure

• 
• angle = 1/2 (arc + arc)

• 
• angle = 1/2 (arc - arc)

• 
• angle = arc measure

• 
• = 90°

• 

match the special types of inscribed angles

• angle in a semicircle

• 
• angles in a quadrilateral

• 
• two inscribed angles with the same arc

• 
• an angle formed by tangent and chord

• 

match the correct equation to solve each problem:

• x = 1/2 (125 - 27)

• 
• x = 1/2 (90 + 200)

• 
• x = 1/2 (32 + 54)

• 
• 2x + (2x + 4) = 180

• 
• 42 = 1/2 (x - 68)

• 

match the equations to solve each problem

• 2x + 16 + x = 180

• 
• angle = 1/2 ((360-112) - 112)

• 
• 2x^2 + 4 = 22

• 
• 112 + x = 180

• 
• P = 2(7 + 4 + 10)

•
