What specific type of shape is quadrilateral
? Justify your conclusion.
Use the Pythagorean Theorem and the triangles shown to determine the lengths of
This will help you determine the type of shape.
What type of quadrilateral (other than a square) has sides all of the same length?
Find the equations of the diagonals
Use slope triangles to find the equations for the diagonals.
Compare the slopes of the diagonals. How do the diagonals of a rhombus appear to be related?
If one line has a slope that is the opposite of the reciprocal of the slope of another line, the two lines are perpendicular.
if quadrilateral is rotated clockwise ( ) about the origin.
