Given: AB ∥CD            ∠ABE = 120°           ∠ECD = 100°           ∠BEC = x°Construction: FEG ∥ABNow, since AB∥FEG and AB∥CD, FEG∥CD∴ EFG∥AB∥CD∠ABE = ∠BEG = 120° (alternate angles)or x°+y° = 120°  ....(i)∠DCE = ∠CEF = 100°   (alternate angles)or x°+z° = 100°   .....(ii)Also, x°+y°+z° = 180°       (FEG is a straight line)   ...(iii)Adding (i) and (ii):2x°+y°+z° = 220°or, x° +180° = 220° (substituting (iii))x° = 40°∴ x = 40. In the given figure, AB || CD, Chapter 13 has problems based on the properties of parallelograms and angles sum property of a quadrilateral. International postal addessing, address formats, and rules. Similarly with angles 5 and 6. Cut AD and SC of length 3.4 cm from AX and BY, respectively. In the adjoining figure, it is being given that AO || CD, OB || CE and ∠AOB = 50° You will also love the ad-free experience on Meritnation’s Rs Aggarwal 2019 2020 Solutions. Similarly with angles 4 and 8, etc. By comparison, a quadrilateral with just one pair of parallel sides is a trapezoid in American English or a trapezium in British English. If two lines are cut by a transversal and the alternate exterior angles are congruent, the lines are parallel. If the slopes are equal, the lines are parallel, and if their product is -1, the lines are perpendicular. Find the measure of each of the angles ∠a, ∠b, ∠c and ∠d. Fig. In the given figure, AB || CD and a transversal EF cuts them at G and H respectively. The three-dimensional counterpart of a parallelogram is a parallelepiped. In the given figure, l || m and t is a transversal.

These solutions for Properties Of Parallel Lines are extremely popular among Class 7 students for Math Properties Of Parallel Lines Solutions come handy for quickly completing your homework and preparing for exams. ∠1+∠2 = 180°                   (linear pair)∴ 5x + 7x = 180                   or 12x = 180or x = 15∴ ∠1 = 5x = 5(15) = 75°and ∠2 = 7x = 7(15) = 105° ∠2+∠3 = 180°                 (linear pair)∠3 = 180-105 = 75°∠3+∠6 = 180                     (interior angles on the same side of the transversal are supplementary)∠6 = 180-∠3 = 105°and ∠6 =∠8 =105°            (vertically opposite angles)∴ ∠1 = 75°      ∠2 = 105°      ∠3 = 75°      ∠8 = 105°. In the context of determining parallelism in Euclidean geometry, a transversal is a line that intersects two other lines that may or not be parallel to each other. That is, when two parallel lines are cut by a transversal, then the sum of adjacent angles is \(180^\circ \). Similarly with angles 5 and 6. If ∠5 = 70°, find the measure of each of the angles In the adjoining figure, it is given that AB || CD, ∠AOB = 50° and ∠CDO = 40°. In the given figure, AB || CD and CA has been produced to E so that ∠BAE = 125°. exterior lines, which do not meet the conic at any point of the Euclidean plane; or; a directrix, whose distance from a point helps to establish whether the point is on the conic.
