    You need to find RD and DQ first because RQ = RD + DQ

    \[DQ=\sqrt{13^2-5^2}\]

    and RD = DQ

    So \[RQ=2\sqrt{13^2-5^2}\]

    With some reasonable asumptions. that RQ is perpendicular to CD

    Then you get an Isosceles triangle.

    You know the value of two sides of triangle DCQ. So you can use the phytagorean theorem.

    Modern geometry is the study of triangles, and circles. Is not that difficult lady.

    We're doing translations, transformations, rotations, etc. And I don't know. You either get geometry or you don't. We've learned about circles and triangles and it was hard for me to understand.

    Well you just have to remember that a squared is formed by perpendicular lines. So they form 90º on each vertex.

    90º + 90º + 90º + 90º = 360º
