<u>Answer : </u>
The value of r in (4,r),(r,2) so that the slope of the line containing them is is 7
<u>Solution: </u>
Slope of the line which is passes through
→ (1)
From question given that two points are (4, r), (r, 2). Hence we get
By substituting the values in equation (1),
→ (2)
Also given that slope that is m = , so on substituting the value of m in equation (2),
On simplifying,
-5r+20=6-3r
5r-3r=20-6
2r = 14
r =7
Hence value of r is 7.

Step-by-step explanation:
Answer:
1 and 2 are not congruent; 1 and 3 are congruent; 1 and 4 are congruent; 2 and 3 are not congruent; 2 and 4 are not congruent; 3 and 4 are congruent.
Step-by-step explanation:
From the diagram, we can see that the angle measures and side measures of figures 1, 3 and 4 are the same. This means that these three figures are congruent. Figure 2, however, is not congruent to any of the other 3.
