Across
- 4. A flat, four-sided shape with at least one pair of parallel sides. The parallel sides are called the bases, while the non-parallel sides are known as the legs.
- 7. The amount of two-dimensional space contained inside the boundary of a flat shape. It measures the size of a surface and is always expressed in square units.
- 8. a part of a line that starts at a specific endpoint and extends infinitely in one direction. It is named using its starting point first, followed by any other point along its endless path.
- 11. Trapezoid A specific type of trapezoid where the non-parallel sides (the legs) are equal in length. This symmetry means its base angles are equal, and its diagonals are also identical in length.
- 12. A flat, four-sided shape where opposite sides are parallel and equal in length. Its opposite angles are also equal, and its consecutive angles add up to 180
- 14. The total distance around the outside edge of a two-dimensional shape. You calculate it by adding together the lengths of all the shape's sides.
- 15. Bisector Line segment that passes thru the midpoint of a segment. Also forms a 90 angle.
- 17. A flat, two-dimensional shape made up of straight, connected line segments that form a closed loop. The points where these line segments meet are called vertices, and the shape must have at least three sides.
- 18. A three-dimensional solid shape bound by flat, polygonal faces that meet along straight edges. These edges intersect at sharp points called vertices, creating a completely enclosed space
- 19. A flat, four-sided shape with two pairs of equal-length sides that are adjacent to each other. Its diagonals intersect at a perfect 90 angle, and one diagonal cuts the other exactly in half.
- 20. The point where the perpendicular bisectors of the sides of a triangle intersect. It is equidistant from all three vertices of the triangle
Down
- 1. Points or lines are geometric elements that lie entirely within the same flat, two-dimensional plane. If a group of geometric figures cannot be contained within a single flat surface
- 2. Three or more points that lie entirely on the same straight line. If a set of points cannot be joined by a single straight line
- 3. A four-sided shape where all four interior angles are equal to 90. It is a special type of parallelogram where opposite sides are parallel and equal in length.
- 5. A flat, four-sided shape with four equal sides and four 90 angles. It is a special type of regular polygon that combines the properties of both a rectangle and a rhombus.
- 6. The total distance around the outside edge of a circle. It is the specific term used for the perimeter of a circular shape.
- 8. A flat, four-sided shape where all four sides have equal length. It is a special type of parallelogram where opposite sides are parallel and opposite angles are equal.
- 9. The geometric center of a shape, representing the average position of all its points. In a triangle, it is the specific point where the three medians intersect.
- 10. A line segment that connects a vertex of a triangle to the midpoint of the opposite side. It divides the opposite side into two equal parts and bisects the triangle's area
- 13. a line segment that starts at a vertex and meets the opposite side at a right angle 90. It represents the perpendicular height of a shape, like a triangle, relative to its base.
- 16. All angles are equal to each other. All sides are equal to each other.
