UnderstandingTwo - Dimensional Shapes

Page 2: 2- D Shapes

An angle is the figure formed by two lines with the same endpoint.

Angles

Page 3: 2- D Shapes

A right angle is an angle with a square corner.

Right Angle

Page 4: 2- D Shapes

Parallel lines are lines that are the same distance apart. Parallel lines do not meet or intersect.

Parallel Lines

Page 5: 2- D Shapes

Plane Figures

Plane figures are figures that are 2-dimensional.

Page 6: 2- D Shapes

Circle

A circle is a curved plane figure in which every point is the same distance from the point at the center.

Page 7: 2- D Shapes

A polygon is a 2-D figure that is closed and whose edges are all straight lines.

PolygonXX

Page 8: 2- D Shapes

A triangle is a shape with three sides and three angles.

Triangle

Page 9: 2- D Shapes

An equilateral triangle is a triangle with three equal sides and three equal angles.

Equilateral Triangle

Page 10: 2- D Shapes

An isosceles triangle is a triangle with two equal sides.

Isosceles Triangle

Page 11: 2- D Shapes

A triangle with a right angle (a square corner).

Right Triangle

Page 12: 2- D Shapes

Quadrilateral

A quadrilateral is a shape that has 4 sides and 4 angles.

Page 13: 2- D Shapes

Kite

A kite is a quadrilateral that looks like a kite -- with no parallel sides, but with two pairs of equal sides that are adjacent to each other.

Page 14: 2- D Shapes

A parallelogram is a figure that has four sides and each pair of opposite sides is equal and parallel.

Parallelogram

Page 15: 2- D Shapes

A rhombus is a parallelogram with four sides of the same length. A square is a special type of rhombus that has all square corners.

Rhombus

Page 16: 2- D Shapes

Square

A square is a quadrilateral that has four equal sides and four right angles.

Page 17: 2- D Shapes

Rectangle

A rectangle is a quadrilateral that has four right angles and each pair of opposite sides is parallel and the same length.

Page 18: 2- D Shapes

A trapezoid is a four-sided shape with only two opposite sides that are parallel.

Trapezoid

Page 19: 2- D Shapes

A pentagon is a figure with five sides. If all angles and sides are equal, then it is regular, otherwise it is irregular.

A hexagon is a figure with six sides. If all angles and sides are equal, then it is regular, otherwise it is irregular.

Octagon

An octagon is a figure with eight sides. If all angles and sides are equal, then it is regular, otherwise it is irregular.
