Determining the Measures of Unknown Angles

T.I.P.S.

Students must be able to use information given about adjacent angles to determine the measure of an unknown angle.

Example

Find the measure of the missing angle and explain how you determined that answer. 

 Hint Possible Solution 

TEKS

Supporting Standard 4.7 Geometry and measurement. The student applies mathematical process standards to solve problems involving angles less than or equal to 180 degrees. The student is expected to: (E) determine the measure of an unknown angle formed by two non-overlapping adjacent angles given one or both measures
