the line p is not a transversal , althought it cuts two lines I and m. Can you say, 'Why' ?

Line l|| m, t is the transversal. angle x = ?

Lines a || b, c is the transversal angle y = ?

Let L_1=0a n dL_2=0 be two fixed lines. A variable line is drawn through the origin to cut the two lines at R and SdotPdot is a point on the line A B such that ((m+n))/(O P)=m/(O R)+n/(O S)dot Show that the locus of P is a straight line passing through the point of intersection of the given lines R , S , R are on the same side of O)dot

AP and BQ are the bisects of the two alternate interior angles formed by the intersection and a transversal t with parallel lines l and m show in figure, show that AP||BQ

Do you find that these two lines are lines of symmetry ?

Paper delievery boy wants to park his cycle at some point P and deliver the newspaper to house A and B . Where should he park the cycle so that his walking distance AP + Bp will be least ? You can use relfection symmetry here . Let A' be the image of A in the mirror line which is the street here . Then the point P is the ideal place to park the cycle . (where the mirror line and A'b meet ) Can you say why ?

If a line is a transversal to three lines, how many points of intersection are there ?

If two interior angles on the same side of a transversal intersecting two parallel lines are in the ratio 2:3, then find the greater of the two angles.

In the fig. p is a transversal to lines m and angle2=120^@ and angle5=60^@ prove that m||n

Suppose two lines are given.How many transversals can you draw for these lines.
