Across
- 2. lines /two lines that are always the same distance apart and never touch.
- 3. / All three sides in one triangle are congruent.
- 4. / Two sides, and the included angle; angle is between 2 marked sides.
- 6. Triangle / triangles that have 3 congruent sides and angles.
- 7. Bisector / line or ray that divides an angle into two congruent angles.
- 9. Interior Angles / angles that don't share a vertex or corner of a triangle with the exterior angle.
- 11. / to turn a figure.
- 12. Property / If a = b and b = c, then a = c.
- 13. two angles whose sum is 90 degrees.
- 15. / The figure formed by three segments joining three noncolinear points.
- 16. Angles / angles that are formed when a transversal passes through two lines.
- 22. Property / states that if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.
- 23. Property/ used when a figure is congruent to itself.
- 24. / Two angles and the included side; side is between 2 marked angles.
- 27. / Only used for right triangles.
- 28. / a mirror image of a figure; to flip over a line.
Down
- 1. /movement/slide on the coordinate plate.
- 3. Addition Postulate / states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
