4th Monthly Test Flashcards
is a line, segment, or ray that cuts another line segment in two equal parts at a right angle
Perpendicular Bisector
It states that if a point lies on the perpendicular bisector of a line segment
equidistant
equidistant
equal distance
a line, ray, or segment that divides an angle into two congruent (equal) angles.
Angle Bisector
an angle bisector divides the opposite side into two segments that are proportional to the lengths of the other two sides.
Angle Bisector Theorem
In a scalene triangle, neither the sides nor the angles are ________
congruent
The longer side is opposite the greater angle
True
sum of the lengths of any two sides must be greater than the length of the remaining side
Triangle Inequality Theorem
Express the Triangle Inequality
Triangle Inequality 1: a + b > c
Triangle Inequality 2: a + c > b
Triangle Inequality 3 b + c > a
when two triangles have congruent corresponding angles, the side lengths opposite the larger angles will be longer in the triangle with the longer angle
Hinge Theorem
the side lengths opposite the smaller angles will be shorter in the angle with the smaller angle.
Hinge Theorem
polygon with four sides and four vertices
quadrilateral

360
quadrilateral in which opposite sides are parallel.
parallelogram
They will never intersect but their slopes are equal
Opposite sides are parallel
