Perpendicular Bisectors

Hi Stacey,

I have another question to ask.

Do "Perpendicular Bisector" problems come on GMAT.

MGMAT Math Guide says it is rare but wanted to check with you.

I am aiming for 700+ in GMAT, do I need to be prepared for this?

Regards,
Sim

Not too much - but the two individual concepts do come up (perpendicular and bisect). Know that when you have two perpendicular lines on a coordinate plane, the slopes of the two lines will be negative reciprocals (that is, change the sign and take the reciprocal). And know that bisect means to cut something in half. If both concepts happen to come up in one problem, you can deal with them separately.

Thanks Stacy for clarifying that.
