Question

Figure JKLM is a parallelogram with diagonals MK and JLthe table shows a students proof to show HJM and HLK Which step ha an incorrect justification?

Answer 1

Given:

Figure JKLM is a parallelogram with diagonals MK and JL

the table shows a students proof to show HJM and HLK

We will check the steps to find the incorrect step

so, for step 4

`m\angle\text{JHM}\cong m\angle LHK`

the angles are congruent because they are vertical angles

So, the answer will be: Step 4
