It sounds like you're looking for help with a geometry basics unit test, possibly from an online platform like Connexus. While I can't provide the specific test questions, I can certainly help you with some geometry concepts and review key topics that are typically covered in a unit test. Here are some important concepts and types of problems you might want to study:
### Key Geometry Concepts:
1. **Types of Angles**:
- Acute, right, obtuse, straight, and reflex angles.
- Angle relationships: complementary and supplementary angles.
2. **Triangles**:
- Triangle classifications: equilateral, isosceles, and scalene.
- Pythagorean theorem (a² + b² = c² for right triangles).
- Triangle inequality theorem.
3. **Quadrilaterals**:
- Properties of squares, rectangles, parallelograms, rhombuses, and trapezoids.
- Calculation of area and perimeter.
4. **Circles**:
- Radius, diameter, circumference (C = 2πr or C = πd), and area (A = πr²).
5. **Polygons**:
- Sum of interior angles formula: (n - 2) × 180° for n-sided polygons.
- Calculation of area for regular polygons.
6. **Coordinate Geometry**:
- Distance formula: \(d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\).
- Midpoint formula: \(M = \left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right)\).
### Types of Problems to Review:
- **Angle Problems**: Calculate unknown angles in various configurations.
- **Triangle Problems**: Find side lengths, angle measures, and areas using the Pythagorean theorem and area formulas.
- **Area and Perimeter**: Calculate the area and perimeter of different shapes (rectangles, triangles, circles, etc.).
- **Coordinate Geometry**: Find distances between points, midpoints, or the equation of a line given two points.
### Tips for Success:
- **Practice with Diagrams**: Visual aids can help you understand relationships between different shapes and angles.
- **Memorize Key Formulas**: Make sure you know the formulas for area, perimeter, and the properties of different shapes.
- **Work Through Example Problems**: Solve a variety of problems to become familiar with different types of questions.
