Answer:
Because it is one of the given pieces of information.
because perpendicular lines form right angles, and all right angles are congruent.
PS and PS are adjacent sides next to the two pairs of congruent angles.
By the Reflexive Property of Congruence
by ASA triangle congruence rule
Step-by-step explanation:
Given the figure of the triangle in the attached image.
Given that;
Because it is one of the given pieces of information.
Then we can observe that;
because perpendicular lines form right angles, and all right angles are congruent.
Also,
PS and PS are adjacent sides next to the two pairs of congruent angles.
And;
By the Reflexive Property of Congruence
Thus,
by ASA triangle congruence rule
