What type of quadrilateral is MATH?
Explain thoroughly how you decided. Your exlanation should NOT be based on how the quadrilateral looks. It should be based on mathematical calulcations like slope and distance formula. Be specific!
Which formula is used to show that segments are congruent?
quadratic formula
slope formula
distance formula
midpoint formula
What do you need to show FIRST before proving a quadrilateral is a rhombus, rectangle or square?
Show it is a parallelogram.
Show it is a triangle.
Show it is a quadrilateral.
Show that it has 4 sides.
Joe drew a line through the points A(-2, 4) and B(7, 5), which equation best represents a line parallel to line AB?
y = -1/9x + 7
y = -9x + 7
y = 9x + 7
y = 1/9x + 7
Given A(-6, 5), B(8, -2), C(6, 10), and D(5, 8), determine what types of lines AB and CD are in relation to each other.
parallel
none of these
