What is a quadrangle figure?
draw a quadrangle below. measure the sides to the nearest 1/2 inch. write the lenght next to each sides. find the perimeter
How do you do the perimeter of a shape?
-- Measure or figure out the length of each side. -- Add up all the lengths of all the sides. -- The answer is the perimeter of the shape.
What is the shape of the twelfth figure?
The shape of the twelfth figure is a dodecagon. A dodecagon is a polygon with twelve sides and twelve angles. It is a regular dodecagon if all its sides and angles are equal. The interior angles of a regular dodecagon measure 150 degrees each.
How do you find the measure of each interior angle of a regular octagon?
Use the equation 180(n-2)/n, where n is the number of sides in the figure.
What is a closed plane figure which has sides that never cross each other?
If none of the sides ever cross each other, there cannot be a closed plane figure.
How many sides would a figure have if it had a measure of 6 degrees for each exterior angle?
It will have 360/6 = 60 sides

Does a quadrilateral have each 4 angles a different measure?
a quadrilateral is any shape with 4 sides, the sides could be any length a rectangle, square and any other figure with four sideds is a quadrilateral
What figure is a polygon?
A polygon is a closed figure of three or more sides. A regular polygon is a figure with straight sides, each side of equal length and all internal angles equal to each other. 3 sides = triangle 4 sides = square 5 sides = pentagon 6 sides = hexagon 7 sides = heptagon 8 sides = octagon 9 sides = nonagon 10 sides = decagon
Which type of triangle has three congruent sides and what do each measure?
An equilateral triangle has three equal sides. The angles of an equilateral triangle measure 60 degrees each, but the sides can be any length.
What is the perimeter of a pentagon if the sides each measure 6 inches?
A pentagon is a 5-sided figure, and the perimeter is the sum of all the sides. If a pentagon has sides of 6 inches, it has 5 x 6 inches = 30 inches for a perimeter.
Square whose sides each measure ten centimeters can completely fit inside of a regular hexagon whose sides each measure ten centimeters?
yes
What is a closed plane figure which has sides that do not cross each other?
polygon
