    Triangle Proof

    Could anyone help me with this 3D figure proof?



    I don't care if its a paragraph proof, a flow proof, or a 2 column proof, whatever floats your boat =D

    Thanks,

    You also know that QC is shared by both triangles so that QC =QC.
    Therefore, you can conclude side angle side.

    Hello, disturbedpanda!




    \begin{array}{cccc}<br />
1. & CR = CS & & \text{Given} \\<br />
2. & QC \perp CR & & \text{Given} \\<br />
3. & QC \perp CS & & \text{Given} \\<br />
4. & \angle QCR = \angle QCS & & \text{d{e}f. of perp.} \\<br />
5. & QC = QC & & \text{Identity} \\<br />
6.& \Delta QCR \cong \Delta QCS & & \text{s.a.s.}\end{array}
