Forming and Solving Equations Involving Angles (B) WORKSHEET
Suitable for Grades: 7th Grade, 8th Grade
CCSS: 7.G.B.5, 8.G.A.5
CCSS Description: Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.
Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles. For example, arrange three copies of the same triangle so that the sum of the three angles appears to form a line, and give an argument in terms of transversals why this is so.

Forming and Solving Equations Involving Angles (B) WORKSHEET DESCRIPTION
Develop students’ understanding of different angle facts by applying them to solve a series of increasingly challenging problems with this worksheet. The problems require students to apply rules for angles around a point, angles on a straight line, and angles in a right angle, building their ability to form and solve equations from geometric figures.
In the first section, students are asked to match pairs of angle facts, reinforcing foundational knowledge such as angles on a straight line summing to 180° and vertically opposite angles being equal.
Following this, the worksheet presents a series of diagrams where students must first state the angle fact they will be using, then form an algebraic equation, and finally solve for the unknown value.
