Question 1.
\nA student attempted to draw a triangle whose rough figure is given here. He drew QR first. Then with Q as centre, he drew an arc of 3 cm and with R as centre, he drew an arc of 2 cm. But he could not get R What is the reason? What property of triangle do you know in connection with this problem?
\nim
\nCan such a triangle exist? (Remember the property of triangles \u2018The sum of any two sides of a triangle is always greater than the third side\u2019!)
\nAnswer:
\nSuch a triangle does not exist, because a triangle is possible only when the sum of the lengths of any two sides is greater than the third side. But here, 2 cm + 3 cm, i.e. 5 cm < 6 cm.<\/p>\n
<\/p>\n
Question 2.
\nIn \u2206ABC if AB = 3 cm, AC = 5 cm and m\u2220C = 30\u00b0. Can we draw this triangle?
\nAnswer:
\nWe may draw AC = 5 cm and \u2220C = 30\u00b0. CA is one arm of \u2220C. But we observe that point B cannot be located uniquely. So, the given data is not sufficient for construction of \u2206ABC.<\/p>\n
Question 3.
\nIn the example (see Page 201, NCERT Textbook), length of a side and measures of two angles were given. Now study the following problem:
\nIn \u2206ABC, if AC = 7 cm, m\u2220A = 60\u00b0 and m\u2220B = 50\u00b0, can you draw the triangle? (Angle sum property of a triangle may help you!)
\nAnswer:
\nWe are given the line segment AC. \u2220A is given but \u2220C is not given. We can determine \u2220C using angle-sum property.
\n\u2220C = 180\u00b0 – (\u2220C + \u2220A).
\n= 180\u00b0 – (60\u00b0 + 50\u00b0)
\n= 180\u00b0 – 110\u00b0 = 70\u00b0
\nNow, with the help of \u2220C, we can construct the triangle.<\/p>\n","protected":false},"excerpt":{"rendered":"
