Question

sss postulate
sas postulate
asa postulate
aas postulate

Explanation:

Step1: Analyze the given triangles

In the two right - angled triangles, we have a right angle (90°), a marked equal angle, and a marked equal side.

Step2: Recall the congruence postulates

• SSS (Side - Side - Side) requires three pairs of equal sides.
• SAS (Side - Angle - Side) requires two sides and the included angle.
• ASA (Angle - Side - Angle) requires two angles and the included side.
• AAS (Angle - Angle - Side) requires two angles and a non - included side.

Here, we have two angles (right angle and the marked angle) and a non - included side (the marked equal side).

Answer:

AAS Postulate
