True
False

Answer 2

4. Refer to the figure to complete the following problem.

Given: *triangle*RST is circumscribed about circle A. What is the measure of angle S ?

*image above*

A. Angle R + angle T
B. 0.5 arc XQ minus arc XPQ
C. 0.5 (arc XPQ - arc XQ)

Answer 3

holy S*** this is.... wow!!!

Answer 4

An inscribed circle is the largest possible circle that can be drawn on the inside of a plane figure. For a polygon, each side of the polygon must be tangent to the circle. All triangles and regular polygons have circumscribed and inscribed circles. Most other polygons do not.

Answer 5

no offense

Answer 6

Okay, so true on 1. Glad for that, cause that's what I thought. :)

Answer 7

Yeah. #2 is also true if you read what I just sent.

Answer 8

Yes, I see that know. Thank you.

Answer 9

3 is false, I think?

Answer 10

Umm #3 I can't tell honestly. It doesn't give us numbers.

Answer 11

Yeah, that's one of the many things I hate about questions like this. Any ideas on 4?

Answer 12

I think 3 is true, which means that angle TRS is also 90..

Answer 13

Okay

Answer 14

And what do you think for #4, I want your opinion.

Answer 15

I want to say A, because it looks the simplest. But at the same time, nothing in this has been simple so I think C.

Answer 16

If that makes sense....

Answer 17

I honestly would go with C.

Answer 18

Alright, thank you!
