  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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
  6. 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.
  7. 15. Bisector Line segment that passes thru the midpoint of a segment. Also forms a 90 angle.
  8. 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.
  9. 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
  10. 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.
  11. 20. The point where the perpendicular bisectors of the sides of a triangle intersect. It is equidistant from all three vertices of the triangle

  1. 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. 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. 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.
  4. 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.
  5. 6. The total distance around the outside edge of a circle. It is the specific term used for the perimeter of a circular shape.
  6. 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.
  7. 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.
  8. 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
  9. 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.
  10. 16. All angles are equal to each other. All sides are equal to each other.
