How do you do this proof? "In circle O, line segment ABC and line segment ADE are secants. Prove that angle ADC is congruent to angle ABE.

This is the diagram:

As I view your figure at that site, it looks like ABC and ADE are NOT line segments. Points B and D are on the circle but not on a line. The two "angles" ADC and ABE do not look like angles in the figure

Use your new 30– 60– 90 and 45– 45– 90 triangle patterns to quickly find the lengths of the missing sides in each of the triangles shown.
