Question | Answer |
---|---|
What is an acute angle? | An acute angle is less than 90 degrees. |
What is Congruent Angles? | Angles that have the same degree. |
What is Coplanar? | Coplanar is when points and lines are in the same plane. |
What is midpoint? | A point that divides a segment into to two congruent segemnts. It bisects the segment. |
What are perpendicular lines? | Lines that intersect to form right angles. |
What is a ray? | A ray is a part of a line that consists of an intial point and all points on the line that lie on one side of the intial point. |
What is a space? | A space is the boundless 3 dimesional set of all points. |
What is an angle? | An angle is made of two rays connected at their end points, called the vertex. |
What are congruent segments? | Congruent segments are segments that have the same length. |
What is an counterexample? | An example that's enough to disapprove a conjecture. |
What is an obtuse Angle? | An angle greater than 90 degrees. |
What is an opposite ray? | A ray that starts at the same point and then goes in opposite directions. |
What are parallel lines? | Lines that are coplanar but do not intersect. |
What is a plane? | A plane is flat surface that has no thickness. It extends without end in all directions. |
What is a point? | A point has no length, no width, and/or no thickness, but has a position. |
What is a postulate? | A statement accepted to be true without proof. |
What is a ray? | A part of a line that consists of an initial point and all points on the line that lies on side of the intitial point. |
What is a right angle? | A angle thats exactly 90 degrees. |
What is a segment? | A portion of a line between two points, called endpoints. |
What is a skew line? | Lines that are colplanar lines, therefore they are not parallel and do not intersect. |
WHat is a space? | The boundless three-dimensional set of all points. |
