Angles!
2. Use a protractor to measure and construct angles. Measure
vertical angles and determine relationship.
3. Name angles in 4 different ways.
4. Using AngLegs, construct acute, right, obtuse, and straight
angles; show complementary angles and supplementary angles,
adjacent and vertical angles.

Draw 2 intersecting lines in your notebook.
Measure and label all the angles carefully.
1. What do you notice?
Opposite angles (or vertical angles) are equal.
The sum of adjacent angles (two angles next to each other)
is 180 degress (supplementary).
The sum of all 4 angles is 360 degrees, a full circle.
2. When measuring angles with a protractor,
how do you know which scale to use? Use
complete sentences to answer.
Start at the base of the angle, which is lined
up with the 0 degree line, and follow that
scale. If the angle is acute, it will measure less
than 90 degrees. If the angle is obtuse, it will
be more than 90 degrees.
