The congruence statement is written as below
Triangle GHK is congruent to triangle JKH by SAS congruence
Triangle WXZ is congruent to triangle YXZ by SAS congruence
What is SAS congruence
IN SAS congruence, two triangles are said to be congruent under SAS congruence if two pairs of corresponding sides are equal in length, and the included angles (the angles formed by the corresponding sides) are equal.
The parts used in the figures are
Side: GH ≅ KJ
Angle: GHK ≅ JKH
Side: HK ≅ KH
Side: WS ≅ XY
Angle: WXZ ≅ YXZ
Side: XZ ≅ XZ
