Geometry vocab

2. angles The angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.
6. angle An angle whose measure is more than 90 and less than 180.
10. polygon A polygon in which all sides are the same length and all angles have the same measure
11. lines Two lines that intersect at right angles; the symbol ⟂ means “is perpendicular to”
12. triangle A triangle with no sides and angles equal in length.
14. Consists of two lines that have a common endpoint called the vertex of the angle.
15. triangle A triangle with all three sides equal in length, each angle of an equilateral triangle measures 60°

1. triangle A triangle with two sides equal in length and two base angles equal.
3. lines Two lines in the same plane that do not intersect ( distance between the two lines is the same at any point).
4. angles Two angles are supplementary if the sum of their measures is 180.
5. angles Two angles are complementary if the sum of their measures is 90.
7. sides Two sides that share a common vertex.
8. A 2-dimensional figure formed by three or more line segments (sides) that meet only at their endpoints (vertices) to make a closed path; sides may not cross one another.
9. The point at which the rays of an angle or the sides of a polygon meet; the plural form of the word is “vertexes” or “vertices”
13. angle An angle whose measure is less than 90 but greater than zero.
16. of symmetry The axis or imaginary line that passes through the center of the shape or object and divides it into identical halves.
