    Question Fun with Triangles - SSA

    In this Challenge I present you with a Red triangle with touching sides of 400px and 300px. The angle of the third side to the 400px base is 30.

    Now the Challenge is to final the second triangle with the same values, as shown:

    The usual rules apply, Xara functions, simplest you can make and with no calculations.
    Here is your starter file: SSA Start.xar

    Marco, I see you cloned the Red trianlge and in the Shaep tool dragged the top node to the circle's edge.

    How do you constrain the angle to remain exactly 30?

    Dragging the node while pressing CTRL key (I usually have the angle constrained at 15 steps, but of course it is possible to constrain them at whatever angle is needed).
    In this case 15 was perfect because you gave us an angle of 30.

    Marco, thank you for the clarification. Your approach does work.

    What I did, was clone the Red triangle.
    Ctrl+Rotate this around the circle's centre so the short side is vertical.
    Then, in the Shape tool, Ctrl+Drag the node from the bottom crossing on the circle to the top crossing.
    Finally, rotate back into position.

    This handles any given angle, or even when none is given, without using Page Options > Document Editing > Angle constraint.
