  • Step 3, point
  • Step 4, point
  • The area of the large square is .
  • Subtracting the area of the 4 right triangles from both sides, we have a, start superscript, 2, end superscript, plus, b, start superscript, 2, end superscript, equals, c, start superscript, 2, end superscript.
  • equals, a, start superscript, 2, end superscript, plus, b, start superscript, 2, end superscript, plus
  • The area of the large square is also a, start superscript, 2, end superscript, plus, b, start superscript, 2, end superscript, plus .
