-a plane figure with four equal straight sides and four right angles.
a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
a plane figure with three straight sides and three angles.
4. Intersecting Lines
Two or more lines that meet at a point
a solid or hollow object that tapers from a circular or roughly circular base to a point.
a solid geometric figure with straight parallel sides and a circular or oval section.
a round solid figure, or its surface, with every point on its surface equidistant from its center.
a solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
a plane figure with eight straight sides and eight angles.
an object, shape, or arrangement in the form of a pyramid.
a flat surface on which a straight line joining any two points on it would wholly lie.
a symmetrical three-dimensional shape, either solid or hollow, contained by six equal squares.
a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides.
a four-sided plane rectilinear figure with opposite sides parallel.
a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
a plane figure with five straight sides and five angles.
17. Angle Bisector
A line that splits an angle into two equal angles.
18. Adjacent Angles
angles that have a common vertex and a common side.
19. Vertical Angles
each of the pairs of opposite angles made by two intersecting lines.
a half of a circle or of its circumference.
An exact location. It has no size, only position.
22. Perpendicular Lines
two lines that meet at a right angle
a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
24. Acute Angle
An angle that measures less than ninety degrees but more than zero degrees.
25. Congruent Circles
Two circles are congruent if they have the same diameter.
