चित्रमा वृत्तको केन्द्रविन्दु O छ । जहाँ AB व्यास, \(\angle BEC = 70^\circ\) र AB//CD छन् ।
In the figure, O is the center of the circle. Where AB is the diameter, \(\angle BEC = 70^\circ\) and AB//CD.
[Figure: Circle with center O, diameter AB, chord CD parallel to AB, point E on circumference, angle BEC = 70 degrees, point X marked]
a) अर्धवृत्तमा बनेको परिधि कोणको नाप कति हुन्छ ? लेख्नुहोस् ।
What is the measure of an angle in the semi-circle? Write it.
b) X को मान निकाल्नुहोस् ।
Find the value of X.
c) कम्तिमा 3 से.मि. अर्धव्यास भएका दुईवटा वृत्तहरू बनाई एउटै चापमा आधारित परिधि कोणहरू बराबर हुन्छन् भनी प्रयोगात्मक विधिबाट परीक्षण गर्नुहोस् ।
Verify experimentally that the angles on the circumference standing on the same arc are equal by making two circles having at least 3 cm radii.
