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.
If a geometric pattern has 17 triangles and squares with a total of 64 sides How many triangles were used?
4 triangles
How many triangles are in a pentagon and how many sides?
A pentagon has 3 triangles and 5 sides
How many triangles make up the shape of a pyramid?
There are 4 triangles that make up a pyramid. 4 on the sides and on the bottom a square or rectangle.
How many sides do 4 dodecagons 4 quadrilaterals and 4 triangles have altogether?
There are 12 sides in a dodecagon, 4 in a quadrilateral, and 3 in a triangle. So in 4 dodecagons, 4 quadrilaterals, and 4 triangles there are 4*12 + 4*4 + 4*3 = 48 + 16 + 12 = 76 sides altogether.
How many sides does a triangular pryimed have that are triangles?
it has 4 sides that are triangles
Are there triangles with 4 sides?
No. Triangles all have three sides.
How many sides do 4 triangles and 4 heptagons have in all?
8
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 triangles are in a pentagon and how many sides?
A pentagon has 3 triangles and 5 sides
How many triangles make up the shape of a pyramid?
There are 4 triangles that make up a pyramid. 4 on the sides and on the bottom a square or rectangle.
Are all squares triangles?
No because squares have 4 sides whereas triangles have 3 sides
How many triangles are formed by drawing diagonals from one vertex of a polygon with fifty sides?
use the formula s-2 (s=sides) there are 2 triangles in a square, which has 4 sides:4-2=2 there are 3 triangles in a pentagon, which has 5 sides:5-2=3 so, there should be 48 triangles in a shape with 50 sides:50-2=48
How many sides do 4 dodecagons 4 quadrilaterals and 4 triangles have altogether?
There are 12 sides in a dodecagon, 4 in a quadrilateral, and 3 in a triangle. So in 4 dodecagons, 4 quadrilaterals, and 4 triangles there are 4*12 + 4*4 + 4*3 = 48 + 16 + 12 = 76 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.
Are right triangles quadrilaterals?
No because all triangles have only 3 sides whereas quadrilaterals have 4 sides.
How many sides are there on 9 triangles?
27. that is, if the triangles are not connected.
