Correct Answer: Option A
Explanation:
A Euclidean compass creates constant radial loci \(\frac{arcs}{circles}\) for geometric angle and bisector constructions.
একটি ইউক্লিডীয় কম্পাস জ্যামিতিক কোণ এবং দ্বিখণ্ডিত নির্মাণের জন্য ধ্রুবক রেডিয়াল লোকি (আর্কস/বৃত্ত) তৈরি করে।
एक यूक्लिडियन कम्पास ज्यामितीय कोण और द्विभाजक निर्माणों के लिए निरंतर रेडियल लोकी (चाप/वृत्त) बनाता है।
Q2
How is a 60° ANGLE (৬০° কোণ) constructed at the endpoint of a ray using ruler and compass?
স্কেল ও কম্পাসের সাহায্যে রশ্মির প্রান্তবিন্দুতে ৬০° কোণ কীভাবে আঁকা হয়?
रूलर और कम्पास का उपयोग करके किरण के अंतिम बिंदु पर 60° का कोण (৬০° কোণ) कैसे बनाया जाता है?
A
Draw an arc with any radius from vertex A intersecting ray at P ; with P as center and SAME RADIUS, cut the arc at Q ; Ray AQ forms 60°শীর্ষবিন্দু থেকে যেকোনো ব্যাসার্ধের বৃত্তচাপ রশ্মিকে P-তে ছেদ করে ; একই ব্যাসার্ধে P থেকে চাপটিকে Q-তে কাটলে কোণটি ৬০° হয়शीर्ष A से किसी भी त्रिज्या का एक चाप खींचिए जो किरण को P पर प्रतिच्छेद करता है; P को केंद्र और समान त्रिज्या लेकर, चाप को Q पर काटें; किरण AQ 60° बनाती है
B
Draw two perpendicular lines and divide by 4দুটি লম্ব রেখা আঁকুন এবং 4 দ্বারা ভাগ করুনदो लंबवत रेखाएँ खींचें और 4 से विभाजित करें
C
Draw an arc with radius 100 cm and divide by 10100 সেমি ব্যাসার্ধ সহ একটি চাপ আঁকুন এবং 10 দ্বারা ভাগ করুন100 सेमी त्रिज्या वाला एक चाप बनाएं और 10 से विभाजित करें
D
Bisect a straight angle 3 timesএকটি সরল কোণকে 3 বার দ্বিখণ্ডিত করুনएक सीधे कोण को 3 बार समद्विभाजित करें
Correct Answer: Option A
Explanation:
In an equilateral triangle, chord length equals arc radius r, subtending exactly \(\theta\) = 60^circ at the circle center.
একটি সমবাহু ত্রিভুজে, জ্যার দৈর্ঘ্য বৃত্তের কেন্দ্রে ঠিক হেটা = 60^বৃত্তকে সাবটেন করে চাপ ব্যাসার্ধ r এর সমান।
एक समबाहु त्रिभुज में, जीवा की लंबाई चाप त्रिज्या r के बराबर होती है, जो वृत्त केंद्र पर बिल्कुल \(\theta\) = 60^circ अंतरित करती है।

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Early practice in middle school builds the mental muscle, speed, and analytical discipline required to ace NTSE, Olympiads, JNVST, Sainik School, and Future Competitive Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
