# Mystery Angles

## Worksheet Description

This worksheet helps students find the values of missing angles 𝑎,𝑏,𝑐 and d in various intersecting line scenarios. Each problem features a set of intersecting lines with some angle measurements provided, and students must determine the unknown angles. By utilizing their knowledge of vertical angles, which are always equal, students can calculate the missing values. Completing this worksheet allows students to practice identifying and solving for vertical angles, strengthening their geometric skills.

The primary math skill this worksheet aims to teach is the calculation of vertical angles, reinforcing the concept that these angles are always equal when two lines intersect. Students will practice recognizing vertical angles and applying this property to find unknown measurements in different geometric setups. Working through these problems enhances students’ problem-solving abilities and deepens their understanding of geometric relationships. Mastering the identification and calculation of vertical angles is crucial for students’ overall comprehension of geometry and prepares them for more advanced mathematical concepts.
