Question | Answer |
---|---|
line | a straight path goes on and on in both directions |
line segment | Two endpoints and a straight path that lies between them |
ray | A part of a line that goes on and on in one direction |
point | A location in space named by an ordered pair |
plane | A flat surface that extends on and on in all directions |
vertices | Vertex is the point where two rays intersect to form an angle. Vertices are more than one vertex. |
parallel | Two lines that always remain the same distance apart, they will never cross. |
perpendicular | Two lines that intersect forming right angles |
intersecting | Two lines that cross at a point |
diagonal | A segment that connects two non-adjacent points on a figure. |
angle | The shape formed when two rays intersect. |
acute angle | an angle that measures less than 90 degrees |
obtuse angle | an angle that measures between 91 and 179 degrees. |
straight angle | an angle that measures 180 degrees |
right angle | an angle that measures 90 degrees |
angle bisector | a ray that divides an angle into two equal sides |
complementary angles | two angles together that equal 90 degrees |
supplementary angles | two angles together that equal 180 degrees |
equilateral triangle | a triangle that has three equal sides and they all equal 60 degrees |
scalene triangle | a triangle that has no equal sides |
isosceles triangle | a triangle that has two equal sides and two angles |
right triangle | a triangle that has a right angle (90 degrees) |
acute triangle | a triangle that has angles that are less than 90 degrees |
obtuse triangle | a triangle that has an angle that is more than 90 degrees |
