200
What are two things, having to do with length and hight, that a math equation will tell you to find in a shape? (lower grade stuff)
Perimeter and area.
200
What is a perpendicular line?
A line that has the oposit angle as another, croses through the other line at a 90 digree angle.
200
What is the line when x=0?
It's horizontal, and has 0 slope.
200

300
What is the area of a 3D object called?
Volume
300
What do points look like when they are collinear?
All in a straight line, or 3 in a row.
300

Triangle ABC is graphed in points A (0,6) B (0,0) C (4,0). Triangle DEF is graphed in points D (2,3) E (0,0) F (4,0).
In Triangle ABC bace=4 hight=6. In Triangle DEF bace=4 Hight=3. Prove DEF is half of ABC.
DEF is half of ABC because 6 is half of 12.
400
Using this triangle, prove its congrence to the other triangle using a 2 colunm proofs. And tell why.
AB=EF given, BC=FG given, CA=GE given
Therefore Tiangle ABCis congruent to triangle EFG, because of S.S.S.
400
What is something that everyone hates dealing with thats in geometry.
Circles and/or pie.

What equation do you use to find slope?
m=y2-y1/x2-x1
400
Triangle ABC is graphed in points A (0,12) B (0,0) C (8,0). Triangle DEF is graphed in points D (4,6) E (0,0) F (8,0).
In Triangle ABC bace=8 hight=12. In Triangle DEF bace=8 Hight=6. Prove DEF is half of ABC.
DEF is half of ABC because 12 is half of 24.

Perimeter: 204 Volume: 4913
500
Image. what lines have the same angle as 1, and same for 2?
1: 4,5,8 2: 3,6,7
500
In the equation y=(x)^2, how else can it be written? (how else can y be written)
f(x)=(x)^2
500
Triangle ABC is graphed in points A (0,18) B (0,0) C (7,0). Triangle DEF is graphed in points D (3.5,9) E (0,0) F (7,0).
In Triangle ABC bace=7 hight= 18. In Triangle DEF bace=7 Hight= 9. Prove DEF is half of ABC.
DEF is half of ABC because 18 is half of 36.
