Answer:
<h2>YES. These points are collinear.</h2>Step-by-step explanation:
If three points are collinear, then the slopes are the same.
The formula of a slope:
For (0, -10) and (-3, -13):
For (-3, -13) and (2, -8):
We can check the last pair (0, -10) and (2, -8):
Answer:
7√2
Step-by-step explanation:
Thank to the give angle we can say that the two legs are congruent
b =
98/2 = 49
49/7 = 7
7/7 = 1
98 = 7^2 x 2
√98 = 7√2
Given that ∠B ≅ ∠C.
to prove that the sides AB = AC
This can be done by the method of contradiction.
If possible let AB =AC
Then either AB>AC or AB<AC
Case i: If AB>AC, then by triangle axiom, Angle C > angle B.
But since angle C = angle B, we get AB cannot be greater than AC
Case ii: If AB<AC, then by triangle axiom, Angle C < angle B.
But since angle C = angle B, we get AB cannot be less than AC
Conclusion:
Since AB cannot be greater than AC nor less than AC, we have only one possibility. that is AB =AC
Hence if angle B = angle C it follows that
AB = AC, and AB ≅ AC.
