Question

math capter 15 ex-15.2 class8​

Answer 1

q1] a] a[4,0],b[4,2],c[4,6],d[4,2.5] -yes all cordinate lie on a line

b] p[1,1],q[2,2],r[3,3],s[4,4] -yes all''''''''on a line

c]k[2,3];l[6,3];m[5,5];n[2,5] -no it doesnot lie on a same line ....

q2] cd is the required point that passes through a and b .now extend the line of a and b so it will meet at x-axis at c[0,5] ;other extent meets at y-axis at d[0,5]

q3] :- coordinates of rectangle oabc are- o[0,0]; a[2,0]b[2,3];c[0,3]

coordinates of parallelogram pqrs :-p[4,3];q[6,1];r[6,5];s[4,7]

co.'''''''''''of triangle klm-k[10,5];l[7,7];m[10,8]

q4]i]true

ii]false ,the point will lie on x-axis on coordinate[5,0]

iii]true
