Geometry in My World By: Hannah Goldfield
Parallel lines are two lines that never meet. They are always the same distance apart.
A cylinder is a solid object with two identical flat ends that are circular and one curved side.
The center of this daisy is the middle point which is the equal distance from all points of the circumference of this circular flower.
A circle is a line that loops around until it joins. Every point is equal distance from the center point. A circle is 360 degrees.
The blue outline on this magnet is the perimeter. A perimeter is the distance of the line that around the edge of the circle.
A square is a 4 sided polygon with equal sides and four 90 degree angles. It is the most common quadrilateral.
A square pyramid is a 3-D shape with a square base and four triangular sides that connect.
An Isosceles triangle has two equal sides and two equal angles.
A Rectangle is a four sided shape with four right angles. Opposite sides are equal and parallel.
Two lines are perpendicular lines when they are at right angles to each other. It makes an upside down T.
A sphere is a 3-D object shaped like a ball.
A right angle is an angle that measures exactly 90 degrees.
A pentagon is a polygon with 5 sides.
A cone is a solid that has a circular base and a single vertex.
A cube is a 3-D solid with six congruent square faces.
A rectangular prism is a solid object which has six faces that are shaped like rectangles.
A protractor is shaped like a half circle. It is an instrument that helps measure and draw
A straight angle is an angle that Measures 180 degrees. It is a straight line.
The diameter of a circle is a straight line going though the center of a circle connecting two points on perimeter.
