Please help me! Please! I am so lost! Pythagorean Theorem!
Ket [755]

Answer:

Part A- yes, because all 3 sides are Equal (each side is 5)

Part B- yes, each rectangle has the dimensions 12*5

Part C- yes- since the sides are 5 and 12 you can determine that the diagonal is 13, using they Pythagorean theorem a^{2} +b^{2} =c^{2}

5^{2} +12^{2} =13^{2} \\25+144=169- true statement, so the lateral sides are rectangles, because the corners are 90

Part D-  4\sqrt{2} (it is a 45-45-90 triangle- so the hypotenuse is the side length times \sqrt{2}

Part E- the diagonal face as the largest area- dimensions are 4\sqrt{2} * 12\\

the area would be 48\sqrt{2}
