Identify the geometric shapes and their properties from the images provided. For each image, describe the shape and list any marked properties like equal sides or angles.

Analysis of Geometric Shapes:

• Image 1:
  • Shape: Quadrilateral ABCD.
  • Properties: The diagonals AC and BD appear to intersect. There are tick marks on segments AD and BC, indicating AD = BC. There are also tick marks on segments AB and CD, indicating AB = CD. There are angle marks at angles DAC and ACB, indicating ∠DAC = ∠ACB. There are also angle marks at angles CDB and ABD, indicating ∠CDB = ∠ABD.
• Image 2:
  • Shape: Quadrilateral PMNK.
  • Properties: The diagonals PN and MK intersect at point K. There are tick marks on segments PK and NK, indicating PK = NK. There are also tick marks on segments MK and PM, indicating MK = PM. There are angle marks at angles MPN and MNP, indicating ∠MPN = ∠MNP.
• Image 3:
  • Shape: Quadrilateral ABCD.
  • Properties: Diagonal AC is drawn. There are tick marks on segments AD and AB, indicating AD = AB. There are also angle marks at angles DAC and BAC, indicating ∠DAC = ∠BAC.
• Image 4:
  • Shape: Quadrilateral ABCD.
  • Properties: Diagonal BD is drawn. There are tick marks on segments AD and BC, indicating AD = BC. There are also tick marks on segments DC and AB, indicating DC = AB. There are angle marks at angles ADB and CBD, indicating ∠ADB = ∠CBD. There are also angle marks at angles BDC and ABD, indicating ∠BDC = ∠ABD.
• Image 5:
  • Shape: A figure formed by three points M, E, D and a point F inside. It appears to be composed of triangles MFD and EFD.
  • Properties: There are angle marks at angles MFD and EFD, indicating ∠MFD = ∠EFD. There are also angle marks at angles DMF and DEF, indicating ∠DMF = ∠DEF.
• Image 7:
  • Shape: Quadrilateral EMNP.
  • Properties: Diagonal EN is drawn. There are tick marks on segments EM and PN, indicating EM = PN. There are also tick marks on segments MN and KP, indicating MN = KP.
