Plane Shape and Measurement

circle

• a two-dimensional shape made by drawing a curve that is always the same distance from a center

• tells the relationship between two or more things

• geometric figures that are identical in size and shape

• a unit of measurement of angles. a full circle is divided into 360 degrees

scale factor

• a number by which all dimensions of an original figure are multiplied to produce a new figure

• a measurement of the amount of rotation between two lines

• the amount of space an object takes up

• more than 90 degrees

Area

• the measurement attribute that describes the number of square units a figure or region covers

• the measurement attribute of the amount of space occupied by matter

•  a polygon with three sides and three vertices

• a three-dimensional figure containing two congruent and parallel faces that are polygons

Congruent

• of equal measure, having exactly the same size and same shape

• two rays with a common endpoint (the vertex)

• a closed figure with at least 3 sides, where all sides are straight (no curves)

• the measurement attribute of the amount of space occupied by matter

Polygon 

• a closed figure with at least 3 sides, where all sides are straight (no curves)

• two rays with a common endpoint (the vertex)

• a three-dimensional figure containing two congruent and parallel faces that are polygons

• the measurement attribute of the amount of space occupied by matter

The plane shapes which have two measurements like length and breadth is known as ——–

• 2D Shapes

• 3D Shapes

• 4D Shapes

• non e of the above

Look at the net ,can it be folded to make a cuboidal box?

• Yes

• No

Tell whether the two figures are congruent.

• Yes, same size and same shape

• No, same shape but different sizes

• No, different size and different shapes

Are these shapes congruent?

• Yes

• No
