Can someone help me with this geometry homework! It’s to do with proofs, Statement and Reasoning.

To prove:
[tex]\Delta\text{CAM}\cong\Delta\text{DBM}[/tex]Statement: 1
[tex]\angle ACM\cong\angle\text{BDM}=90^{\circ}[/tex]Reason: Given
Statement:2
[tex]\angle CMA\cong\angle DMB[/tex]Reason:
Angle 1 and angle 2 are congruent angles.
And also,
[tex]\begin{gathered} \angle CMA\cong\angle1(\text{Alternate angles)} \\ \angle DMB\cong\angle2(\text{Alternate angles)} \end{gathered}[/tex]Statement: 3
[tex]AM=MB[/tex]Reason: M is the midpoint of AB.
Statement: 4
[tex]\Delta\text{CAM}\cong\Delta\text{DBM}[/tex]Reason: By AAS congruence.
Hence proved.
