Sample Topics and Practice Questions for Jan 23 Geometry Regents
Sample Multiple Choice Question
In a triangle, if two angles are 45° and 60°, what is the measure of the third angle?
- 75°
- 85°
- 90°
- 105°
Answer: 75° (since the sum of angles in a triangle is 180°, so 180° - 45° - 60° = 75°)
Sample Construction Problem
Construct an equilateral triangle given a segment AB. Use a compass and straightedge to complete the construction.
Sample Word Problem
A circle has a radius of 7 cm. Find the length of an arc that subtends a 60° central angle.
Solution: Use the formula for arc length: \( \text{Arc length} = \frac{\theta}{360} \times 2\pi r \)
Arc length = \( \frac{60}{360} \times 2\pi \times 7 \) = \( \frac{1}{6} \times 14\pi \) ≈ 7.33 cm
Conclusion: Excelling in the Jan 23 Geometry Regents
Success on the Jan 23 Geometry Regents requires a combination of conceptual understanding, practical skills, and test-taking strategies. Consistent practice and thorough review of key topics will prepare students to approach the exam with confidence. Remember that understanding the underlying principles, practicing problem-solving, and managing time effectively during the test are crucial.
