Question

Segment TC is perpendicular to segment AB. If AB=28 cm, what is the length of segment DA? (I'll upload an image)

Answer 1

Theorem:

If a radius of a circle is perpendicular to a chord, then it bisects the chord.

if AB = 28, then what is DA? @kaioken360

Answer 2

`bisect` is another way of saying `cut in half`

you can bisect segments into two equal pieces
you can also bisect angles into two equal pieces
