Given: △abc≅△def, △klm≅△def prove: △abc≅△klm set up as a two-column proof. there are three triangles they are equal to each other. triangle 1: ∠a, ∠b, ∠c triangle 2: ∠d, ∠e, ∠f triangle 3: ∠k, ∠l, ∠m

Simply 8x squared + 5(7x squared- x) - 2x =

Is trapezoid abdc the result of a dilation of trapezoid mnpq by a scale factor of ? why or why not? yes, because ab and cd are each the lengths mn and qp. yes, because sides ab and cd are parallel to sides mn and qp. no, because ab is the length mn but cd is the length qp. no, because sides ab and cd have different slopes from sides mn and qp.
