2: A line has one dimension. It extends without end in two directions. It is represented by a line with two arrowheads.
3: A segment consists of the endpoints A and B, and all points on AB that are between A and B.
4: In geometry, figures intersect if they have any points in common. An intersection of two or more figures is the point or points that the figures have in common.
5: An acute triangle has a measure of 0 to 90 degrees.
6: A right angle has a measure of exactly 90 degrees.
7: An obtuse triangle has a measure between 90 and 180 degrees.
8: An angle consists of two rays with the same endpoint.
9: A segment bisector is a segment, ray, or plane that intersects a segment into two congruent segments at its midpoint.
10: An angle is complementary if the sum of their measures is 90 degrees.
11: Angle is supplementary if the sum of their measures adds up to 180 degrees.
12: An angle is vertical if they are not adjacent and their sides formed two intersecting lines.
13: An angle is parallel when the lines lie in the same plane and do not intersect.
14: An angle is formed by a transversal when a line that intersects two or more coplanar lines at different points.
15: A line is perpendicular when a line intersects to form a right angle.
16: A triangle is a three-sided polygon.
17: An angle measurement is how many degrees an angle is.
18: A polygon is a plane figure that is formed by three or more segments called sides.
19: The Pythagorean Theorem is in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the length of the legs.
20: If (x1, y1) and (x2, y2) are points in a coordinate plane, then the distance between A and B is
21: Congruent triangles have the same shape, size, and measure. We can tell they are congruent by SSS, SAS, ASA, AAS, and HL.
22: A parallelogram is a four-sided polygon.
23: A square is a four-sided polygon.
24: A rhombus is a parallelogram with four congruent sides.
25: A rectangle is a parallelogram with four congruent angles.
