<\/p>\n
Question 2. \nDraw rough sketches for the following: \n(a) In \u0394ABC, BE is a median. \n(b) In \u0394PQR, PQ and PR are altitudes of the triangle. \n(c) In \u0394XYZ, YL is an altitude in the exterior of the triangle. \nAnswer: \n(a) In the \u0394ABC, \\(\\overline{\\mathrm{BE}}\\) is the median. \n <\/p>\n
(b) In the right \u0394QPR, \\(\\overline{\\mathrm{PQ}}\\) and \\(\\overline{\\mathrm{PR}}\\) are altitudes of the triangle. \n <\/p>\n
(c) In the figure, \\(\\overline{\\mathrm{YL}}\\) is an altitude of \u0394XYZ. \n <\/p>\n
<\/p>\n
Question 3. \nVerify by drawing a diagram if the median and altitude of an isosceles triangle can be same. \nAnswer: \n \nABC is an isosceles triangle having \nAB = AC …(i) \nDraw its median AD. \nConsider \u0394ADB and \u0394ADC \nAB = AC (By (i)) \nAD = AD (Common) \nBD = DC \n(Since AD is median) \n\u21d2 \u0394ADB = \u0394ADC (SSS) \n\u21d2 \u2220ADB = \u2220ADC = 90\u00b0 \n(Corresponding angles) \n\u2220ADB = 90\u00b0 \n\u2235 \\(\\overline{\\mathrm{AD}}\\) is a perpendicular to \\(\\overline{\\mathrm{BC}}\\). \nThus, \\(\\overline{\\mathrm{AD}}\\) is the median as well as the altitude of \u0394ABC.<\/p>\n","protected":false},"excerpt":{"rendered":"
