Karnataka State Syllabus Class 7 Maths Chapter 5 Lines and Angles Ex 5.2<\/h2>\n

Question 1.
\nState the property that is used in each of the following statements ?
\n\"KSEEB
\ni) If a || b, then \u22201 = \u22205
\nSolution:
\nThe two parallel lines a & b are cut by a transversal then \u22201 = \u22205 because they are corresponding angles. So they have equal measure.<\/p>\n

ii) If \u22204 = \u22206, then a || b.
\nSolution:
\nIf \u22204 and \u22206 are equal measures they are interior alternate angles. So. a is parallel to b.<\/p>\n

iii) If \u22204 + \u22205 = 180\u00b0, then a || b.
\nSolution:
\nHere two parallel lines are cut by transversal, \u22204 and \u22205 are pairs of interior angles on the same side of the transversal are supplementary.<\/p>\n

\"KSEEB<\/p>\n

Question 2.
\nIn the adjoining figure, identify
\n\"KSEEB
\ni) the pairs of corresponding angles.
\nSolution:
\nThere are 4 pairs of corresponding angles,
\na) \u22201 and \u22205
\nb) \u22202 and \u22206
\nc) \u22204 and \u22208
\nd) \u22203 and \u22207<\/p>\n

ii) the pairs of alternate interior angles.
\nSolution:
\nThere are 2 pairs of alternate interior angles. They are
\na) \u22203 and \u22205
\nb) \u22202 and \u22208<\/p>\n

iii) the pairs of interior angles on the same side of the transversal.
\nSolution:
\nThere are 2 pairs interior angles on the same side of the transversal, they are
\na) \u22203 and \u22208
\nb) \u22202 and \u22205<\/p>\n

iv) the vertically opposite angles.
\nSolution:
\nThere are 4 pairs of vertically opposite angles. They are
\na) \u22201 and \u22203
\nb) \u22202 and \u22204
\nc) \u22205 and \u22207
\nd) \u22206 and \u22208.<\/p>\n

\"KSEEB<\/p>\n

Question 3.
\nIn the adjoining figure, p || q. Find the unknown angles.
\n\"KSEEB
\nSolution:
\nThe unknown angles are
\n\u2220e = 180\u00b0 – 125\u00b0 = 55\u00b0 (supplementary angles)
\n\u2220f = \u2220e = 55\u00b0 (\u2235 vertically opposite angles)
\n\u2220a = \u2220e = 55\u00b0 \u2220b = 125\u00b0
\n\u2220c = \u2220a = 55\u00b0 (\u2235 vertically opposite angles)
\n\u2220d = \u2220b = 125\u00b0<\/p>\n

\"KSEEB<\/p>\n

Question 4.
\nFind the value of x in each of the following figures if l || m.
\nSolution:
\n\"KSEEB<\/p>\n

Question 5.
\nIn the given figure, the arms of two angles are parallel. If \u2220ABC = 70\u00b0, then find
\nSolution:
\n\"KSEEB
\ni) \u2220DGC
\n\u2220DGC = \u2220ABC = 70\u00b0
\nii) \u2220DEF
\n\u2220DEF = \u2220ABC = 70\u00b0<\/p>\n

\"KSEEB<\/p>\n

Question 6.
\nIn given figures below, decide whether l is parallel to m.
\ni) \"KSEEB
\nl is not parallel to m. ( \u2235 the sum of the angles are not supplementary. 126 + 44 = 170 \u2260 180)<\/p>\n

ii) \"KSEEB
\nl is not parallel to m<\/p>\n

iii) \"KSEEB>
\nl is parallel to m
\n(\u2235 123 + 57 = 180)<\/p>\n

iv) l is not parallel to m.
