Label a point G on segment EF and construct a line perpendicular to EF through point G. Draw segments EG and FG. C. Construct the perpendicular biesector of segment EF. Mark the intersection of this line and EF and label it G. Draw segments EG and FG. D. Construct the perpendicular bisector of segments EF. Mark any point G on the perpendicular bisector except where it intersects EF. Draw segments EG and FG.

la. let A= 2. and a. what is the dimension of COIA? b. what is the rank of A? C. Is W in COIA?

Are the two triangles depicted similar? Explain. A.  The two triangles are similar since a dilation of △ABC, with the origin as the center of dilation and a scale factor of 3, maps it onto △DEF. B.  The two triangles are not similar since a dilation does not preserve the interior angle measures of a triangle. C.  The two triangles are not similar since a dilation does not preserve the side lengths of a triangle. D.  The two triangles are similar since a dilation of △ABC, with the origin as the center of dilation and a scale factor of 1/3, maps it onto △DEF.
