Answer:

SAS stands for "side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal. If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.Side-Angle-Side (SAS) Rule

Side-Angle-Side is a rule used to prove whether a given set of triangles are congruent. so..

dlinksuman: if we have to prove this triangle is of 90 degree, so do we have to prove these two congruent first?

navdeepkaur240306: yeah you're right !! ...we have to prove two congruent first

dlinksuman: OK

dlinksuman: thank you so much

navdeepkaur240306: and for that you need to use formula
