Question

Can u help me
What other information do you need to know in order for these triangles to be congruent based on HL?

Answer 1

The diagram shows that FG = IJ are congruent segments due to the double tickmarks. These are the hypotenuses of the right triangles.

So that takes care of the "H" in "HL".

The L stands for "leg", so we need to have a congruent pair of corresponding legs.

Due to the orientation of the triangles, it's not clear how the corresponding legs match up, but if any of the following is true

• EF = IK
• EF = JK
• EG = IK
• EG = JK

then we'd have enough to use HL.
