Ok so I need help understanding how to do indirect proofs. I'm so confused. :/

Given: quad. EFGH in which m. of angle EFG=93; m. of angle FGH=20; m. of angle GHE=147; m. of HEF=34
Prove: EFGH is not a convex quad


My teacher wants it in a 5 listed proof exactly like this:
1. Assume temporarily that....
2.Then....
3.But this contradicts the known or given fact that...
4.Therefore are temporary assumption that... .... is false.

For time t, in hours, 0 t 1, a bug is crawling at a velocity, v, in meters/hour given by the following equation:
V= 1/(0.83 + t)
Use delta t = 0.2 to estimate the distance that the bug crawls during this hour. Find an overestimate and an underestimate. Then average the two to get a new estimate.
meters (overestimate) =
meters (underestimate) =
meters (new estimate) =

What would the graph of the following equation of a conic section look like?

x^2/9 + y^2/25 = 1

Would it be vertical ellipse, horizontal ellipse, vertical hyperbola, or horizontal hyperbola?



Describe the graph of the following equation:
(x-2)^2/36 + (y-1)^1/36 = 1
Would it be circle with the center in the first quadrant with radius 6, circle with center in the second quadrant with radius 36, circle with center in the third quadrant with raduis 6, or circle with center in the fourth quadrant with radius 36?


Given the equation of the ellipse below, find the local points.

x^2/25 + Y^2/9 = 1
Would it be (5,0) and (-5,0), (4,0) and (-4,0), (0,3) and (0,-3), or (5.83,0) and (-5.83,0)?

This is the second time I've posted this question. I've already received a good answer from the first time I posted. The problem is that I forgot to say that I only have like 2 minutes for the problem. Once again.... NO CALCULATORS are allowed.
The question is below and the answer I got before is also below to help out.


There is a boy who is standing at the center of a circular field that had a radius of 135 feet. He walks due north halfway to the circle. He then turns and walks due east half way to the circle. He turns again and walks due south half way to the circle. Finally he turns and walks due west half way to the circle. When he stops, how many feet is the boy from the center of the circle? Round the answer to the nearest foot.
