Conversion works similarly, OPT-click on the square box.
And, like Illustrator, with the pen tool, click=linear point, click+drag=bezier with the standard pen tool.
But Photoshop has the "curvature pen tool" which will automatically create custom bezier paths.
Draw the first curve and whilst on the second point press the Alt key (Opt on Mac).
Move the second handle to point in the direction of the straight line.
Click on your third point
