Question

pls answer the third. I'll mark u brainliest!​

Answer 1

Answer:

in triangle AOB and triangle SOR

RS =AB ( given)

angle ORS = angle OBA ( alternative angles )

angle OSR = angle OAB ( same)

triangle AOB is congruent to triangle SOR ( ASA criterion)

as OR =OB ( corresponding side of a congruent angle )

O is the mid point of BR

Answer 2

Answer:

please mark me as brainliest

Step-by-step explanation:

In this figure

AB is parallel to RS

O is the mid point AS which shows that AO=OS

we have to find that

triangle AOB is congruent to triangle SOR

AB = RS (given)

Angle ROS=Angle AOB (vertically opposite angle)

AO=OS (showed above)

so by SAS criteria triangle AOB is congruent to triangle SOR

and

O is the mid point because as we know that angle is also equal from O in both the triangles and O is the mid point of AS and AB = SR then by taking these measures if we will make the diagram we will find that O is also the mid point of RB.
