Measuring angles

TEKS

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:

4.7.A - illustrate the measure of an angle as the part of a circle whose center is at the vertex of the angle that is "cut out" by the rays of the angle. Angle measures are limited to whole numbers;

4.7.C - determine the approximate measures of angles in degrees to the nearest whole number using a protractor;

4.7.D - draw an angle with a given measure; and

4.7.E - determine the measure of an unknown angle formed by two non-overlapping adjacent angles given one or both angle measures.

This week our kiddos have to measure angles with protractors.

The way I remember complementary and supplementary angles is that it feels RIGHT to give a complement and supplementary and STRAIGHT both start with S.
