Kari drew two parallel lines PQ and RS intersected by a transversal KL, as shown below.Which fact would help Kari prove that the measure of angle QMN is equal to the measure of angle SNL?

Question

anonymous · Answer

Interior angles MNR and PMN are congruent to each other and vertical angles SNL and MNR are congruent to each other.

 Alternate interior angles MNR and QMN are congruent to each other and vertical angles SNL and MNR are congruent to each other.

 Alternate interior angles MNS and PMN are supplementary and vertical angles SNK and RNL are congruent to each other.

 Interior angles MNR and PMN are supplementary and consecutive angles SNL and MNS are congruent to each other.

What is the name of the two angles marked in the picture?

anonymous · Answer

@Mertsj which angles?

mertsj · Answer

The ones with the arcs on them.

triciaal · Answer

I know they are corresponding angles because they occupy corresponding positions  when formed by two lines and a  transversal.

anonymous · Answer

mq and ns

triciaal · Answer

we  always identify an angle with 3 letters   
qmn   the angle in  the  middle formed by  the lines from the "outside "  letters  qm and mn

triciaal · Answer

how  would  you name   the other angle? sn is a line
