∠KPL ≅ ∠MRL as perpendicular always makes an angle of 90°.
<h3>What specifically is meant by "triangle congruency"?</h3>
When two triangles' three corresponding sides and angles are the same sizes, they are said to be congruent.
These triangles can be moved, rotated, flipped, and turned to look exactly the same.
They will coincide if they are moved.
Congruence exists when two triangles satisfy the five congruence conditions.
They are the side-side-side (SSS), the side-angle-side (SAS), the angle-side-angle (ASA), the angle-angle-side (AAS), and the right angle-hypotenuse-side (RHS).
So,
Given: ∠ K ≅ ∠M, KP⊥ PR, MR ⊥ PR
To Prove: ∠KPL ≅ ∠MRL
As MR ⊥ PR (Given), then: ∠MRL = 90°
Similarly, KP⊥ PR (Given), then: ∠KPL = 90°
So, ∠KPL ≅ ∠MRL.
Therefore, ∠KPL ≅ ∠MRL as perpendicular always makes an angle of 90°.
