How many sides do 3 hexagons and 3 nonagons have altogether?
A hexagon has six sides, and a nonagon has nine. Three hexagons and three nonagons then have (3 x 6) + (3 x 9) = 18 + 27 = 45 sides altogether.
The characteristics of triangles squares rectangles parallelograms quadrilaterals pentagons hexagons and octogons?
Squares, rectangles, and parallelograms all fall under the category of "quadrilateral" simply because they all have four sides; however, quadrilaterals must also be two-dimensional, and all of its sides must be straight. Squares must have four equilateral sides--with opposite sides parallel to each other-- and each angle must be a right angle (90 degrees). Rectangles are like squares in that each angle must be a right angle, and opposite sides must be parallel, but all four sides need not be equal to each other in length; rather, only opposite sides are equal in length. Parallelograms must have opposite sides that are equal in length and parallel to each other, as well as opposite angles that are equal to each other, but these angles are not right angles. Triangles, pentagons, hexagons, and octagons all fall under the category of "polygon" because they are two-dimensional figures made of straight lines, but do not have four sides like quadrilaterals. Triangles must have three sides and three angles that add up to 180 degrees. Pentagons have five sides, hexagons have six sides, and octagons have eight sides.
What are two regular pentagons?
Jasmine drew 2 pentagons Compare the 2 pentagons that Jasmine drew. Tell how they are alike, and identify three ways that they are different.
How many sides do six triangles have?
A triangle has three sides, so six triangles have 6 * 3 = 18 sides altogether.
How many sides do 5 decagons and 4 triangles have altogether?
A decagon has ten sides and a triangle has three, so 5 decagons and 4 triangles have (5*10)+(4*3) = 62 sides altogether.
How many sides do 3 quadrilaterals and 5 pentagons have altogether?
37 sides
How many sides do 2 hexagons 2 pentagons and 1 triangle have altogether?
There are six sides in a hexagon, five in a pentagon, and three in a triangle. So in 2 hexagons, 2 pentagons, and 1 triangle there are 2*6 + 2*5 + 1*3 = 12 + 10 + 3 = 25 sides altogether.
Quadrilaterals are polygons that have three sides?
Quadrilaterals are polygons with four sides. Triangles are polygons with three sides.
Do polygons have at least four sides?
No. A triangle is a polygon and that has three sides. A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons.
How many sides do 3 hexagons and 3 nonagons have altogether?
A hexagon has six sides, and a nonagon has nine. Three hexagons and three nonagons then have (3 x 6) + (3 x 9) = 18 + 27 = 45 sides altogether.
How many sides do 4 heptagons 2 quadrilaterals and 3 triangles have altogether?
A heptagon has seven sides, a quadrilateral has four, and a triangle has three. So 4 heptagons, 2 quadrilaterals, and 3 triangles have 4*7 + 2*4 + 3*3 sides = 28 + 8 + 9 sides = 45 sides.
How many sides does 3 pentagons have?
Three pentagons have a total of 15 sides. Each pentagon has 5 sides, so when you have 3 pentagons, you would multiply 5 sides by 3 pentagons to get 15 sides in total.

How many sides do 1 decagon 5 quadrilaterals 5 octagons and 5 triangles have altogether?
A decagon has ten sides, a quadrilateral has four, an octagon has eight, and a triangle has three. So in 1 decagon, 5 quadrilaterals, 5 octagons, and 5 triangles there are 1*10 + 5*4 + 5*8 + 5*3 = 10 + 20 + 40 + 15 = 85 sides altogether.
How many sides do a nonagon and a triangle have altogether?
A nonagon has nine sides, and a triangle has three, so altogether they have 12 sides.
