252 The coordin<strong>at</strong>es of the vertices of ABC A(1,3),<br />

B(−2,2) and C(0,−2). On the grid below, graph<br />

and label A″B″C ″, the result of the composite<br />

transform<strong>at</strong>ion D 2 T 3,−2 . St<strong>at</strong>e the coordin<strong>at</strong>es of<br />

A″, B″, and C ″.<br />

253 In the diagram below, which transform<strong>at</strong>ion was<br />

used to map ABC to A′B′C ′?<br />

1) dil<strong>at</strong>ion<br />

2) rot<strong>at</strong>ion<br />

3) reflection<br />

4) glide reflection<br />

254 Write an equ<strong>at</strong>ion of the perpendicular bisector of<br />

the line segment whose endpoints are (−1,1) and<br />

(7,−5). [The use of the grid below is optional]<br />

255 In the diagram below of ABC, DE is a<br />

midsegment of ABC, DE = 7, AB = 10, and<br />

BC = 13. Find the perimeter of ABC.<br />

256 In right DEF, m∠D = 90 and m∠F is 12 degrees<br />

less than twice m∠E . Find m∠E .
