Question 62664: I Don't Understand Gemetry Proofs. Could You Send Me Information On How To Do Them?
Answer by checkley71(8403)   (Show Source):
You can put this solution on YOUR website! Geometry is a vast subject.
Need a little more information like:
What is your specific needs TRIANGLES (area,perimeter, angles, patagorian theorem [a^2+b^2=c^2], etc.)
RECTANGLES (area, perimeters, diagonals, etc.)
CIRCLES (circumferance, area, chords, angles, etc.)
GRAPHING lines using the line formula (Y=mX+b), finding the slope of a line, finding the line formula when you have two points or a point & a slope.

Present a speciofic area & I'm sure we'll be able to asist you master whatever!!!!!!!!

The key to solving angles within triangles is: the sum of all three angles is 180 degrees.
The most common triangles is the 45/45/90 & 30/60/90.
If your given two fo the angles say 40 & 50 then assign the unknown angles x then 180=35+40+x
180=75+x
180-75=x
x=105
---------------------------------------------------------
Another example would be one angles is 15 more than the second and the third is 45 less than the first. Let x be the first angle then the second is (x+15) and the third is (x-45). Now just add these three angles and set the sum = to 180 thus:
x+(x+15)+(x-45)=180
x+x+x+15-45=180
3x=180-15+45
3x=210
x=210/3
x=70
proof
70+(70+15)+(70-45)=180
70+85+25=180
180=180
