Question

luffingsails · Answer

Statements 2 and 3 are saying the same thing but referencing different measurements. If Statement 3 is talking about the measurement of angle D... what angle do you thing Statement 2 is referencing?

ellamoyseyuk · Answer

A = m<A = 1/2 arcs BC
B =The measure of an inscribed angle is half the measure of its intercepted arc.
C=Corresponding angle Postulate.

@luffingsails is that correct or not

luffingsails · Answer

Perfect start!

luffingsails · Answer

So, (b) is the same reason as for Statement 2. Right?

ellamoyseyuk · Answer

yes it is @luffingsails

luffingsails · Answer

Right so, now look at statement 4 in relationship to statement 5. They are saying very much the same thing. I think if you look up the definition of congruent you will be able to use that for the reason in place of (c).

ellamoyseyuk · Answer

Two inscribed angles that intercept the same arc are congruent.

luffingsails · Answer

Close, instead (c) would be "two angles whose measurements are equal are congruent." The following on statement that can be made from the proof is exactly what you wrote, "Two Inscribed Angles that intercept the same arc are congruent."
