Answer:
The Proof is given below.
Step-by-step explanation:
Given: 
LN⊥KM,
KL≅ML 
To Prove: 
ΔKLN≅ΔMLN
Proof:
In  Δ KLN and Δ MLN
KL ≅ ML     ....……….{Given i.e Hypotenuse }
LN ≅ LN     …………..{Reflexive Property}
∠ LNK ≅ ∠ LNM  ……….{ LN ⊥ KM i.e Measure of each angle is 90° given}
Δ KLN ≅ Δ MLN     ….{By Hypotenuse Leg Theorem}
....Proved
 
        
             
        
        
        
A bar graph is a chart that uses bars to show comparisons of different types of data. The bars can either be horizontal or vertical. They are always straight if I’m not mistaken
