Question

In the given figure, if a = b and x=y then prove that l || n. please answer properly :>

Answer 1

Step-by-step explanation:

a= b so l || m as a,b are corresponding angles

x=y and x,y are alternate interior angles so m||n

thus l || m || n and l || m

Answer 2

Answer:

angle (a) is equal to angle (b) {a=b corresponding angle}

therefore line l and m are parallel

and angle(x) is equal to angle (y)

this means line m is parallel to n {x=y alternate

angles}

since line l is parallel to m and

line m is parallel to n

therefore line l is parallel to n
