∆abc is translated 2 units down and 1 unit to the left. then it is rotated 90° clockwise about the origin to form ∆a′b′c′.

the coordinates of vertex a′ of ∆a′b′c′
the coordinates of vertex b′ of ∆a′b′c′ are
the coordinates of vertex c′ of ∆a′b′c′ are

the perimeter is increased by a factor of 2

“ 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 .
