Recognize that angles at a point on a straight line total 180 degrees.
Know that angles are measured in degrees and that one whole turn is 360 degrees. Calculate angles at a point.
Use angles at a right angle and use perpendicular lines. Spot right angles of any orientation on a square grid. Understand the term complementary angles. Also use the rule that angles on a straight line at a specific point sum to 180. Solve problems involving straight line angles. Understand the term supplementary angles. Also use the rule that angles at a point sum to 360. Known as a full turn..
Recognize and calculate with vertically opposite angles. The term 'opposite' will be acceptable.
Understand that when parallel lines are crossed by another line, corresponding angles are created. Solve problems involving the corresponding angles. The term 'F' angle is not sufficient to explain why 2 angles are equal.
Understand that when parallel lines are crossed by another line, (interior) alternate angles are created. Solve problems involving the alternate angles including understanding the properties of allied angles, although this term is not examined. The term 'Z' angle is not a sufficient reason for two angles being equal.
