Term
adjacent angles
Definition

Because they share a side, but don't overlap, we refer to angles XNT and TNO as ____________________.

Term
verticle angles
Definition

When two lines intersect they form four angles. A pair of those angles that are opposite each other are known as ______________________________.

Term
complementary angles
Definition

One angle measures 47°, and another measures 43°. Based on their sum, we would refer to them as ______________________________.

Term
supplementary
Definition

One word to describe two angles whose sum is 180 degrees is "______________________________."

 

Term
bisector
Definition

Line AB intersects segment EG at point F, cutting segment EG into two equal parts. Line AB is called the ______________________________ of segment EG.

Term
perpendicular bisector
Definition

Not only does a ________________________________________ divide a segment into two congruent segments, it also makes a 90 degree angle with the segment.

Term
angle bisector
Definition

Draw an angle in the space below this question. Now draw a ray that starts at the angle’s vertex and divides the angle into two congruent angles. ________________________________________ is the name we give to this ray.

Term
conjecture
Definition

Mrs. Bruning observes several boys simply stuffing handouts into their backpacks. Based on her observation, she says, “Boys stuff handouts into their backpacks.” Mrs. Bruning has just made a(n) ______________________________ about the behavior of boys.

Term
theorem
Definition

We proved that the sum of the interior angles of a triangle is 180 degrees. So the underlined statement is a(n) ______________________________.

Term
proof
Definition

When you use deductive logic to write an argument that a statement is true, we call that argument a(n) ____________________.
