    you would use the pythagorean theorem a^2 + b^2 = c^2 6^2 + 8^2 = x^2 solve for x

    6^2+8^2=100^2=10,000

    it should be 6^2 + 8^2 = 10^2

    \[\large 6^2 + 8^2 = x^2\] \[\large 36 + 64 = x^2\] \[\large 100 = x^2\] \[\large x^2 = 100\] \[\large x = \sqrt{100}\] \[\large x = 10\]

    if two triangles are congruent, what can we say about their corresponding parts?
