Answer:
<h2>Reflection.</h2>Step-by-step explanation:
The image attached shows a representation of the problem, there you can observe the congruence between triangles.
Also, using the images you can easily deduct the transformation we need to map one triangle onto the other one, we just need to reflect one triangle across and axis that pass through point M, such line acts like a mirror.
Therefore, the right answer is reflection.
Given:
Consider the three number are given by:
To find:
The three numbers are the Pythagorean triple generated by using 4 for x and 1 for y.
Solution:
We have,
Substituting 4 for x and 1 for y, we get
Similarly,
And,
The three three numbers are the Pythagorean triple are 8,15 and 17.
Therefore, the correct option is C.
Answer:
fourth option
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 3)² + (y - 7)² = 2 ← is in standard form
with centre = (h, k) = (3, 7) and r² = 2 ⇒ r =
