Geometry Proof Vocab 2
Across
- 3. these are given statements that prove a mathematical concept is true and are composed of two parts.
- 4. these are lines or sides of a shape that intersect to form 90 degree angles.
- 7. this property means that a number or side length is always equal to itself.
- 11. big ideas that are accepted as universal truths without proof.
- 14. sides or angles that are located in the same position and with the same measurement for polygons with an equal number of sides.
- 16. when a number of object is replaced with an equivalent one.
- 17. a claim made in reference to a figure or math concept.
- 18. the supporting evidence for the respective statement made that must be theorems, properties, or other rules accepted by the math community.
- 19. this property of equality states that if two numbers of variables equal one another, then they must also equal each other. Ex: if a = b and b = c, then a = c.
Down
- 1. a __________ angle has a measure of 180 degrees.
- 2. when two angles whose measures have a sum of 90 degrees they are _____________.
- 5. these are lines in the same plane that never intersect or meet.
- 6. these nonadjacent angles are formed by two intersecting lines.
- 8. a statement that has been proven or can be proven using math reasoning.
- 9. this is a line intersecting a system of lines, usually a set of parallel lines.
- 10. an object is said to have _______________ if it can be divided into two identical halves.
- 12. these two angles’ measures have a sum of 180 degrees.
- 13. similar to a postulate, this is something that is accepted as true without proof.
- 15. when two figures, shapes, or objects have the same size and shape.
- 16. shapes that are ________ are resized versions of the same shape.
