O Side BC is congruent to side EF. Look at the figure below: A 7 4 B C What is the length, in units, of segment CD? O 5.50 O 12.25 O 8 O 14In a quadrilateral ABCD, the diagonals intersect at point T. Heather has used the Alternate Interior Angles Theorem to show that angle ABD is congruent to angle CDB and that angle BAC is congruent to DCA. Which of the following can Heather use prove that segment DT is equal to segment TB? O AB = DC OAC = DB O DA = BC OAC = ACIf j = h and k = m, then which expression represents the value of g? A E h g D k B m O g= = Og = 2f Og =_ O g = K mTia used a photocopier to dilate the design for a monorail track system. The figure shows the design and its photocopy: G Design Photocopyr The ratio of DA:HE is 1:2. ll.iiihat is the length. in meters, of side F6 on the photocopied image? Which statement is not used to prove that AABC is similar to AADE? C E D B A O AC is a transversal line passing ED and CB. O Angle A is congruent to itself, due to the reflexive property. O Segments ED and CB are parallel. O The sum of angles A and B are supplementary to angle C.The ABC Toy Company is creating two similar pieces for a board game, as shown. How could the toy maker confirm that the pieces are similar using a transformation? E A D C O Verify ZA = _D and E by translation. O Verify AB = DE and BC = EF by translation. O Verify ZA = > D and zB = >E by reflection. O Verify AB = DE and BC = EF by reflection.In ACAB, point E is the midpoint of E and point D is the midpoint of 36- It the measure of E is 8 units. what is the measure of segment E? A O 3 units O4units O 5 units O 5 units SQRT is a parallelogram. If _ STR = 106, which of the following statements is true? R U S T O Z RTU = 530 O Z QUR = 74 O Z QST = 106 O Z RQS = 106Below is a two-column proof incorrectly proving that the three angles of APQR add up to 180*: Statements Reasons Z QRY = _ PQR Alternate Interior Angles Theorem Draw line ZY parallel to PQ Construction m Z ZRP + m Z PRQ + m Z QRY = m Z ZRY|Angle Addition Postulate Z ZRP = Z RPQ Alternate Interior Angles Theorem m Z RPQ + m Z PRQ + m Z PQR = m Z ZRY| Substitution m Z ZRY = 180* Definition of a Straight Angle m Z RPQ + m Z PRQ + m Z PQR = 180 Substitution Which statement will accurately correct the two-column proof? O The measure of angle ZRY equals 180 by definition of supplementary angles. O Angles QRY and PQR should be proven congruent after the construction of line ZY. O The three angles of APQR equal 180 according to the Transitive Property of Equality. O Line ZY should be drawn parallel to segment QR.The vertices of AMNO are M (1, 3), N (4, 9), and O (7, 3). The vertices of APQR are P (3, 0), Q (4, 2), and R (5, 0). Which conclusion is true about the triangles? O The ratio of their corresponding sides is 1:2. O The ratio of their corresponding angles is 1:2. O They are similar by the definition of similarity in terms of a dilation. O They are congruent by the definition of congruence in terms of rigid motions.If a translation maps z D onto
