Angles
MD.5 Recognize angles as geometric shapes that are formed where two rays share a common endpoint.
a) Understand that an angle is measured with reference to a circle with its center at the endpoint.
b) Understand that an angle that turns is measured by that turn.
MD.6 Measure angles in whole-number degrees using a protractor.
MD.7 Recognize angle measure as additive.
a) Understand that when an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the parts.
b) Solve addition and subtraction problems to find unknown angles on a diagram in real-world and mathematical problems.
