Can we have a median from vertex A which is perpendicular to BC but does not bisect the angle A? No. Angle bisector which is also a median implies isosceles triangle which implies it is also the altitude. Can we have an angle bisector which is also a median which is not perpendicular? No. Should an angle bisector in a triangle which is also a median be perpendicular to the opposite side? Yes. Try to prove all these properties on your own. In an equilateral triangle, each altitude, median and angle bisector drawn from the same vertex, overlap. – If median drawn from vertex A is also the angle bisector, the triangle is isosceles such that AB = AC and BC is the base. Hence this altitude is also the angle bisector. – If altitude drawn from vertex A is also the median, the triangle is isosceles such that AB = AC and BC is the base.
Hence this angle bisector is also the altitude. – If angle bisector of vertex A is also the median, the triangle is isosceles such that AB = AC and BC is the base. The reverse of what we just learned is also true. – the bisector of the angle opposite to the base is the altitude and the median. – the median drawn to the base is the altitude and the angle bisector – the altitude drawn to the base is the median and the angle bisector In an isosceles triangle (where base is the side which is not equal to any other side): We will now give you some of these properties which can be very useful. And, as always, any time you can identify a triangle as a special triangle, you have even more rules you can apply to better understand it.
But, importantly, in special triangles such as isosceles and equilateral triangles, they can overlap. Usually, medians, angle bisectors and altitudes drawn from the same vertex of a triangle are different line segments. Median – A line segment joining a vertex of a triangle with the mid-point of the opposite side.Īngle Bisector – A line segment joining a vertex of a triangle with the opposite side such that the angle at the vertex is split into two equal parts.Īltitude – A line segment joining a vertex of a triangle with the opposite side such that the segment is perpendicular to the opposite side. To begin, we are assuming you know the terms median, angle bisector and altitude but still, just to be sure, we will start our discussion today by defining them: So in today’s post, let’s discuss these interesting triangle concepts as a group and show how they can be applicable to challenging GMAT geometry questions. Send us feedback.No concept group on GMAT geometry questions is more important than triangles, and no discussion of triangles on the GMAT would be fully comprehensive without covering medians, altitudes, and angle bisectors.
