3 The student can measure the given angles to within 2 degrees of the actual measurement and identify each angle, with 95% accuracy 2 The student is able to measure the given angles to within 10 degrees, and is able to identify the angles with 95% accuracy 1 Student is unable to correctly measure the given angles and/or identify the angles correctly
The sum of the measures of the angles in any triangle in the plane is 180 degrees. If two angles are 15 and 85 then their sum is 100 degrees and 180-100=80 degrees
Since the sum of the internal angles of a plane triangle is 180 degrees, the measure of the missing angle is 65 degrees. 180 - 74 - 41 = 65 degrees.
Yes the 3 interior angles, 2 of which are acute angles, of an obtuse triangle add up to 180 degrees
44 degrees
