5th Ch 12 Angles Review

Name the Angle

100

<WXY or <YXW

200

Name this angle

<ABC or <CBA

300

Name the smallest angle

<BCD or <DCB

400

Name the red angle

<ABC or <CBA

500

Name the red and blue angles

Red = <AOC or <COA

Blue = <BOC or <COB

Measure it

100

18^o

200

35^o

300

128^o

400

140^o

500

Measure the red and blue angles

Red = 25^o

Blue = 45^o

Angles at a Point

100

Find the missing angle?

220^o

200

What is the angle measure of the rest this figure?

130^o

300

97^o

400

56^o

500

29^o

More Angles

100

Name the angle type (angles on a line, angles at a point, vertical angles) and explain the rule

angles at a point = 360^o

200

Name the angle (angles on a line, angles at a point, vertical angles) and explain the rule

Vertically opposite angles are equal

300

Name the angle (angles on a line, angles at a point, vertical angles) and find b

vertical angles are equal therefore

b = 40^o

400

Name the angle (angles at a point, vertically opposite or adjacent angles) and the missing angle

angles at a point = 360^o

e = 17^o

500

Name the angle (angles on a line, angles at a point, vertical angles) and find x

Angles on a line

360 - 90 - 90 - 50 - 30 = 100

x = 100^o

Grab bag

100

What is x?

x = 105

200

180 - 45 = 135^o

300

Find the m<CAD

58 - 32 = 26^o

400

Find O

90 - 51 = 39

O = 39^o

500

90 - 62 = 28^o
