Mathematics

IJ = LM.

Step-by-step explanation:

The Side-angle-side postulate states that if the pair of a corresponding sides and angles formed between these sides of two triangles are equal in measurement then these two triangle are said to be congruent.

As shown in figure 1 below:

In Δ HIJ and ΔKLM,

∠I = ∠L = 20° and HI = KL = 5 units

Since the ∠I lies between HI and IJ and ∠L lies between KL and LM, ∴ if IJ = LM then Δ HIJ and ΔKLM will be congruent by SAS postulate.

Angle i measured 20 degrees, side hi = 5, angle l = 20 degrees, and side kl =5. what additional info
