Transcript and Presenter's Notes

Section 4-7

- Medians, Altitudes and Perpendicular Bisectors

Median

- connects the vertex to the midpoint of the

opposite side

Thus, every triangle has three medians.

Altitude

- the perpendicular segment from a vertex to a line

that contains the opposite side

- For obtuse triangles, two altitudes fall outside

the figure. - You extend the base of the triangle so that it

intersects the altitude at a right angle.

For obtuse triangles, there is still one altitude

in the triangle.

In Right Triangles Two of the altitudes lie on

the legs of the triangle. The 3rd is inside.

Perpendicular bisector of a

segment

- is a line (or ray or segment) that is

perpendicular to the bisector at its midpoint

In a given plane, there is exactly one

perpendicular to a segment at its midpoint

Theorem 4-5

- If a point lies on the perpendicular bisector of

a segment, then the point is equidistant from the

endpoints of the segment

Theorem 4-6

- If a point is equidistant from the endpoints of a

segment, then the point lies on the perpendicular

bisector of the segment.

Theorem 4-7

- If a point lies on the bisector of an angle,

then the point is equidistant from the sides of

the angle.

Theorem 4-8

If a point is equidistant from the sides of an

angle, then the point lies on the bisector of the

angle.
