Across
- 4. each of the pairs of opposite angles made by two intersecting lines. Vertical is similar to the vertex of two triangles
- 7. straight lines passing through to create an endpoint. It is 2 or more lines.
- 9. part of a line consisting of two endpoints and all points in between. It is written like EF, AD, RK, QR etc.
- 11. slides an object from a fixed distance or direction. It is also an isometric transformation that maps every point to an image.
- 12. the ratio between corresponding measurements of an object and a representation of that object. If the scale factor is a whole number, the copy will be larger.
- 13. value of something compared to another thing. A example is one apple to one orange, 1:1
- 14. a polygon which is inscribed in a shape. It can be especially a cyclic polygon, which is inscribed in a circle and a midpoint polygon of another polygon.
- 16. two points that form and line with no thickness or width. Some say it is a dot that went for a walk.
- 18. intersecting system of lines. It is what the alternate, corresponding and consecutive angles lie on.
- 20. two figures are said to. be similar. if they are the same shape. More specifically if they are congruent triangles.
- 21. a location of the graph. It has no shape or size.
- 22. a flat surface made up of points.It would be three or more points.
- 23. angles formed when two lines intersect. They are linear if they a formed by two intersecting lines.
Down
- 1. two angles sum is 180 degrees.For example one angle is 150 degrees and the other is 30 degrees.
- 2. Angles formed when two parallel or non-parallel lines are intersected by a transversal. The angles are positioned at the inner corners of the intersections and lie on opposite sides of the transversal angle.
- 3. having all its sides the same length. This would be a triangle and it could be congruent.
- 5. A reflection is a transformation representing a flip of a figure. When reflecting a figure in a line or in a point, the image is congruent to the pre image.
- 6. when the shape changes in size. An example is when a triangle gets really small and compresses.
- 8. of something into two equal or congruent parts, usually by a line. This line is then called a bisector.
- 10. pair of angles that lie on the outer side of the two parallel lines. But on either side of the transversal line.
- 15. an isometric transformation that maps every point to an image. A example is point P to point P' and it is reflected off of a y or x axis.
- 17. two ratios that are set equal to each other. Usually the ratios in proportions are written in fraction form
- 19. isometric transformation that also maps every point to an image. It turns a figure about a fixed point which is called center of rotation.
