cm draw an arc above AB. Step-3. With B as centre draw an arc to cut the arc drawn in step 2 at pt C. Step-4. Join AC and BC. Step-5. With A and C as centre and radius 4.5 cm draw arcs to intersect each other at D. Step-6. ABCD is required rhombus. Checking: Verify your figure by adopting some other property of rhombus. Step 1. Join BD to intersect AC as O. Step 2. Measure ∠AOB. Is it 90°? Step 3. Measure OA and OC. Are they equal? Step 4. Measure OB and OD. Are they equal? If your answer to 2, 3, 4 is yes it means what you have constructed is a right angle. 1. Can you draw this rhombus by using some other property? 2. Can you draw a parallelogram with given measurement? 3. How will you construct this rhombus if instead of side 4.5 cm diagonal 4.5 cm is given? In questions 1 to 52, there are four options, out of which one is correct. Write the correct answer. 1. If three angles of a quadrilateral are each equal to 75°, the fourth angle is
- (a)150°
- (b)135°
