Topic: Finding Unknown Angles

Learning objectives: Students will be able to use  supplementary, complementary, vertical, and adjacent angles to find unknown angles  .In addition, they will be able to use facts ( such as the measurement of the supplementary , complementary, vertical, and adjacent) angles to solve multi steps problem ( that require students to do several steps for example finding X , students will need to do these steps 1. adding two angles together. 2. Subtracting them from the angle measurement in order to find to fix the measurement of X) and to solve simple equations for unknown angle in a figure ( find the X angle in the figure for example (x+30=90).
