① If two angles are identical, they are vertical angles. ② If AB=BC, B is the midpoint of AC. ③ If each two of three straight lines intersect, there must be three intersections. ④ In one plane, there is only one straight line perpendicular to the known straight line through a po...
A line contains the points (3, -4) and (5, 2). Another line graphed in the same coordinate plane contains the points (0, 5) and (-2, -1). Based on the slopes of these lines are they parallel, perpendicular or neither? Determine the plan...
are equal. (iii)Two lines perpendicular to the same line are perpendicular to each other. (iv)Two lines parallel to the same line are parallel to each other. (v)If two parallel lines are intersected by a transversal, then the interior angle on the same side of the transversal are equal...
Answer to: Prove: In a plane, if two lines are parallel to a third line, then the two lines are parallel to each other. By signing up, you'll get...
Find the slopes of the straight lines. kx+4y−2k=0 4y=−kx+2k y=−k4x+k2…(1) slope=−k4 6x−9y+4=0 −9y=−6x−4 y=−6−9x−4−9 y=23x+49 slope=23 由于它们互相垂直,因此斜率的积=−1, Since they are perpendicular, the product of the slopes is =...
No matter what kind of linework you do, always hold your brush perpendicular to the skin. Get the right paint consistency. Getting the right paint consistency will help you obtain vibrant colors and sharp lines. Creamy and inky paint consistencies are what you want for linework. Use creamy ...

1a). These results are in line with the intra- and intertumoral heterogeneity often ascribed to CSCs20. To assess whether this phenomenon was exclusive of the murine cancer model, we treated human osteosarcoma (U2OS), breast carcinoma (MCF7, HMLER) and mammary epithelial (MCF10A) cell lines ...
