Geometry Vocabulary

3. An angle whose measure is between 180 and 360 degrees
4. An infinite set of points with no endpoints extending endlessly in both directions; represented by a line using two points with the symbol above it
6. 2 angles that are supplementary that form a straight angle
9. Dot, no distance; a location in space; no dimensions (length, width, height); usually name a point with capital letter
12. A triangle in which no two sides have the same length and no two angles have the same measure
13. Angle whose measure is between 0 and 90 degrees
14. An angle who measure is exactly 180 degrees; a line
15. An angle is formed from two rays that share an endpoint; the rays are called its sides, and the ending is called the vertex
16. Two angles whose measures equal 180 degrees

1. Two angles whose measures equal 90 degrees
2. An angle whose measure is between 90 and 180 degrees
5. 2 angles that share a common vertex and a common side
7. An angle who measure is exactly 90 degrees
8. All the sides and all the angles are congruent.
10. A pair of angles opposite from one another formed by two intersecting lines
11. A triangle in which two sides are congruent and two angles are congruent. The two congruent sizes are called legs. The third side is called the base. The two congruent angles are called base angles. The third side is called the vertex angle.
