Question

given: the coordinates of triangle PQR are (0,0), Q(2a,0), and R(2b,2c). Prove: the line containing the midpoints of two sides of a triangle is parallel to the third scale. as part of the proof find the midpoint of QR

Answer 1

connect (a,0)~(b,c)
the tangent of it is c/(b-a) connect (2a,0)~(2b,2c)
tangent is equal

Answer 2

huh

Answer 3

so whats the answer

Answer 4

Answer 57

what is the reflection image of p(0,0) after two reflections, first across x=-3 and then across y=4

Answer 58

across x=-3 it becomes (-6,0) and across y=4 it becomes (-6,8)

Answer 59

triangle XYZ is reflected across line x=3. what is the reflection of image x

Answer 60

if f starts at (-1,5)

Answer 61

f?

Answer 62

i ment x

Answer 63

(7,5)

Answer 64

if r is at -3,2 and it reflects across the y axis

Answer 65

Well, first i will give you this tip that when (x,y) is across x=a, it is (2a-x,y)

Answer 66

same with y=a

Answer 67

thedoptions are
-2,0
0,2
3,2
-3,-2

Answer 68

so it would be 3,2

(7,-2)

Answer 71

wich rule describes a transformation across the x-axis.
the options are;
(x,y)(-x,y)
(x,y) (-x,-y)
(x,y) (y,x)
(x,y) (x,-y)
