Now add relations and a tangent arc.

1. Click Select on the Standard toolbar, then hold down Ctrl and select the vertical lines on each side of the lower arc.
2. In the PropertyManager, under Add Relations, click Equal , then click OK .
   The Equal relation ensures that both vertical lines will maintain equal length.
3. Click Tangent Arc on the Sketch tab, then click the endpoint of the lower vertical line.
4. Move the pointer downward to create an arc that has an angle of 90° and a radius of approximately 60mm. Click to place the arc.
   
5. Sketch another tangent arc. Move the pointer until the endpoint of the arc is coincident with the endpoint of the bottom horizontal line as shown.
