What have we got to prove? Whether we have to prove a triangle as an Isoseles triangle or prove a property of an isoseles triangle. Hey, do u go to ALHS, i had that sam…e problem on my test today. Greenehornet15@yahoo.com
the circumcenter, orthocenter, and centriod, when connected together i Euler's line. the angle bisector of the non base angle is the same thing.
Which types of triangles must always have at least one angle bisector that is also a perpendicular bisector?
iscoceles triangle! =)
If the bisector of the vertical angle of the triangle bisects the base prove that the triangle is isosceles?
show that the bisector of the vertical angle of an isosceles triangle bisects the base
thank goodness for my math teacher, norm! he said only in an isosceles triangle. The bisector of the vertex angle of an isosceles triangle is perpendicular to the base! =)
Why are the median angle bisector and altitude from the vertex angle of an isoceles triangle all the same?
It's in the definition of an angle bisector: An angle is formed by two rays with a common endpoint. The angle bisector is a ray or line segment that bisects the angle, creatin…g two congruent angles. and an isoceles triangle: it is a triangle with (at least) two equal sides. This property is equivalent to two angles of the triangle being equal. An isosceles triangle therefore has both two equal sides and two equal angles.
For what kinds of triangles can the perpendicular bisector of a side also be an angle bisector of the angle opposite the side?
Every isosceles or equilateral triangle.
An isosceles or an equilateral triangle perhaps?
Does the angle bisector of the vertex angle of an isosceles triangle divides the triangle into two congruent?
Only if the vertex angle being bisected is between the sides of equal length will the result be two congruent triangles.
The right way
No. The angle bisector is a line. Where the three lines meet is the median. In an equilateral triangle the INTERSECTION of the angle bisectors is the median.
In an isosceles triangle if a base angle has a measure of 43 degrees then the vertex angle must have a measure of 80 degrees as well true or false?
False because if each base angle is 43 degrees then the apex angle must be 94 degrees
