|
Each line segment has only one bisector that is also perpendicular to the segment. What is it called?
|
Perpendicular Bisectors
|
|
|
What does equidisant mean?
|
The same distance, from two endpoints of a line segment.
|
|
|
If a point is equidistant from these endpoints of a segment, then it is on the of the what of the segment?
|
Perpendicular Bisectorof the segment.
|
|
|
What is a median of a triangle?
|
The segment connecting the vertex of a triangle to the midpoint of its opposite side is a median.
|
|
|
How do you find the median of a triangle?
|
Find the perpendicular bisector of a side and the connect where it crosses the side to the vertex across the side.
|
|
|
The segment that connects the midpoints of two sides of a triangle is called what?
|
midsegment
|
|
|
How do you fine the perpendicular bisector with Patty paper?
|
Fold the segment onto itself, so that end points line up the crease is the perpendicular bisector.
|
|
|
Define distance?
|
The distance from a point to a line is the length of the perpendicular segment from the point to the line.
|
|
|
What is an altitude of a triangle?
|
An altitude of a triangle is a perpendicular segment from a vertex to the to a line containing the opposite side.
|
|
|
How many altitudes does a triangle have?
|
The length of the altitude is the height of the triangle. A triangle has three different altitudes (heights.)
|
|
|
How do you make a angle bisector with patty paper?
|
Fold your patty paper so that rays coincide and crease the paper along the fold. The fold is the bisector
|
|
|
How do you construct a angle Bisecting?
|
Make an arc across both rays. Make an X with an arc from each point thath the first arc crosses the rays.
|
|
|
Classify this triangle?
|
Acute because all angles are less than 90 degrees.
|
|
|
Classify this triangel?
|
Obtuse because at least one angles is more than 90 degree.
|
|
|
Classify this triangel?
|
Right triangle because one angle is 90 degrees.
|
|
|
What is a scalene triangle?
|
A triangle with no sides the same length.
|
|
|
What is a isosceles triangle?
|
A triangle with two sides the same length.
|
|
|
What is a equilateral triangle?
|
A triangle with all the sides the same length.
|
|
|
What is a circumcenter of a triangle?
|
It is where the 3 perpendicular bisectors of each side cross.
|
|
|
Where can the circumcenter of a triangle be located?
|
Inside outside and on the triangle.
|
|
|
What is a circumcenter of a triangle?
