Measurement & Geometry

4. A quadrilateral with four equal sides; opposite angles are equal and diagonals bisect each other at right angles in a rhombus.
7. the measure from one side of a circle across to the opposite side
8. The amount of space inside a 3 dimensional figure
9. A quadrilateral with at least one pair of parallel sides; the parallel sides are called bases.
10. The total area of all faces of a 3 dimensional figure
12. A four-sided polygon; the sum of its interior angles is 360^\circ.
13. A quadrilateral with two pairs of parallel sides; opposite sides are equal in length and opposite angles are equal.
14. the measurement from the center of a circle to the edge
15. Figures that are the same shape and size; corresponding sides and angles are equal.

1. The multiplier used in a dilation; if the scale factor is k, lengths become k times their original lengths. If k>1 the image enlarges; if 0<k<1 the image reduces.
2. Figures with the same shape but not necessarily the same size; corresponding angles are equal and corresponding side lengths are proportional (have a constant ratio).
3. A two-dimensional plane defined by perpendicular axes (x-axis and y-axis) used to locate points with ordered pairs (x,y).
5. A rectangle with four equal sides; a quadrilateral that is both a rectangle and a rhombus.
6. A parallelogram with four right angles; opposite sides are equal and adjacent sides are perpendicular.
7. A transformation that resizes a figure from a center of dilation by a scale factor; distances from the center are multiplied by the scale factor.
11. A segment connecting two nonadjacent vertices of a polygon; in quadrilaterals, there are two diagonals.
