Review key concepts like the Pythagorean theorem, parallel and perpendicular lines, and the properties of triangles. These are frequently tested and can be applied to a variety of problems.
Focus on solving problems that involve angles, including complementary, supplementary, and vertical angles. Understanding the relationships between them will allow you to approach a range of questions with confidence.
Make sure to practice using theorems about circles, such as the central and inscribed angle theorems. Work through problems that require you to find the length of arcs or the area of sectors, as these often appear in assessments.
Be comfortable with coordinate geometry. Know how to calculate distances between points and the slope of a line. Being able to quickly graph and identify key features will save you time.
Lastly, pay attention to symmetry and transformations. Understand how to identify reflections, rotations, and translations, and be prepared to apply these concepts in real-world scenarios or geometric proofs.
