I cannot access and provide specific content from copyrighted materials like the CBE (Computer-Based Examination) practice tests. Sharing such materials would be a violation of copyright and potentially unethical. However, I can offer you information and strategies to help you prepare for the geometry portion of the CBE Practice Test B, assuming it covers standard high school geometry topics.

This guide offers strategies and information to help you succeed on the geometry section of your CBE practice test. Remember, consistent study and practice are key!

Key Geometry Topics Commonly Tested

Most high school geometry exams, including likely the CBE, cover these core concepts:

1. Lines, Angles, and Triangles

Types of Angles: Acute, obtuse, right, straight, complementary, supplementary, vertical. Understanding angle relationships (e.g., angles on a straight line sum to 180°) is crucial.
Triangle Properties: Classify triangles (scalene, isosceles, equilateral, acute, obtuse, right). Know the Pythagorean theorem (a² + b² = c² for right triangles), triangle inequality theorem (sum of any two sides > third side), and properties of similar triangles (corresponding angles are equal, corresponding sides are proportional).
Lines and Planes: Parallel lines and transversals (alternate interior angles, corresponding angles, consecutive interior angles). Understanding perpendicular lines and their relationship to slopes.

2. Polygons and Quadrilaterals

Polygon Properties: Know the formulas for the sum of interior angles of a polygon ( (n-2) * 180° where n is the number of sides). Understand regular polygons (all sides and angles equal).
Quadrilaterals: Be familiar with the properties of parallelograms, rectangles, rhombuses, squares, trapezoids, and kites. Know their unique characteristics and how to prove a quadrilateral is a specific type.

3. Circles

Circle Properties: Understand radius, diameter, circumference, area, arc length, sector area, central angles, inscribed angles. Know the relationship between inscribed angles and their intercepted arcs.
Tangents and Secants: Understand the properties of tangents (perpendicular to the radius at the point of tangency) and secants (lines intersecting a circle at two points).

4. Coordinate Geometry

Distance Formula: Calculate the distance between two points in a coordinate plane.
Midpoint Formula: Find the midpoint of a line segment.
Slope: Calculate the slope of a line and understand its relationship to parallel and perpendicular lines.
Equation of a Line: Write equations of lines in slope-intercept form (y = mx + b) and point-slope form.

5. 3-Dimensional Geometry (Possible, but less likely a major focus in a high school geometry test)

Surface Area and Volume: Calculate the surface area and volume of prisms, pyramids, cylinders, cones, and spheres.

Strategies for Success

Practice, Practice, Practice: Work through as many geometry problems as possible. Focus on problems similar to those you expect to see on the CBE.
Review Formulas: Make a list of important formulas and review them regularly. Don't rely on memorization alone; understand how the formulas are derived.
Identify Weak Areas: As you practice, identify areas where you struggle. Focus your study time on these areas.
Use Diagrams: Draw diagrams to visualize problems. This can help you understand the relationships between different parts of a geometry problem.
Check Your Work: Always check your work carefully. Make sure your answers make sense in the context of the problem.

This information should help you prepare. Remember to consult your textbook, class notes, and any other materials provided by your instructor for specific details relevant to your CBE practice test. Good luck!
