An used the Pythagorean Theorem to find the distance between two points as follows. 2²+ b² = ²
[11 - 2)² + (3 – 15)² = c²
ng² + (-12)2 = c²
81 + 144 = 2
225 = 62
C = 15
Which of these pairs of points could he have been finding the distance between?
(2, 15) and (11, 3)
(-2, -15) and (11,3)
(11, -2) and (3.-15)
(11.2) and (3, 15)

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

just go here

its what i use

step-by-step explanation:

11) obtuse

13)right

15) acute
