Line AC is perpendicular to the circle centered at O with radius 1 unit.

The length of AC is 1.5 units. Find the length of segment AB. (Round your answer to the nearest tenth.)

Find the missing length. Round your answer to the nearest tenth.

The image shows a circle with diameters AC and BD.

Prove that chords BC and AD (not drawn) are congruent by organizing the statements and reasons to form a correct proof.
