whats this shape called its  like an half triangle?

it should have a right angle.\n\nThus, it's a right triangle

Cut either in half diagonally and you have two identical triangles when one is rotated 180 degrees.\n\nThe sum of the four angles is 360 degrees for both\neach of the four angles is 90 degrees for both\n\nYou can make a square deal using rectangle shaped dollar bills.\n \nwhen either is given a third dimension it can be called a block.

Well, a rectangle is not a triangle it is a parallelogram, I think. It has four right angles and two long sided and two short sides. Therefore, the dimensions are as follows: To figure area it is short side * long side. To figure how long all sides are you simply do two short sides plus two long sides. However, I am assuming that this was trick question to see who is paying attention to what a rectangle is.

It is called regular polygon.

it would be called tangent...if it touches the outside of the circle once.\n\nthe radius of the circle is a line that goes through the cirlce half way, the diamiter is a line that goes through the circle and cuts it right in half, so the radius is half the diamiter.\n\nsecant intersects a cirlce at two points.\n\nSO the answer is tangent.\n\nhope this helps.

Yes. Right triangles have them all the time. it's called the orthocenter i think....it's been a while since Geometry.

The shape with 120 sides is called Hexakis Icosahedron.\n\nThe Hexakis Icosahedron has 62 vertices, 120 faces and 180 edges. (The Hexakis Icosahedron is the only polyhedron with 120 faces.) \n\nThe Hexakis Icosahedron contains 120 triangles. \n\nThe dual of the Hexakis Icosahedron is the great rhombicosidodecahedron. \n\nI hope I answered your question. All the best.

i think it's a parabola.. im not sure. u should try plotting it on a graph.. substitute  the x and y values and see what form comes out..

Do you mean like an object that has a semi-circle on one end?\n\nIf yes, you can find the area of the semi-circle by figuring the area of the entire circle and dividing by half. Then you just find the area of the rectangular portion and add the two answers.

There are two names for a seven sided shape, heptagon and septagon.  Both answers are equally correct

The Area of a triangle is half the area of a square. So take one verticy and take a 90degree line from that up to the other corner.\n\nOh cr@p I'm starting to forget it all now. Too long ago.\n\nIt's something like that.

HEPTAGON - a seven-sided polygon.\n\nTRIANGULAR PYRAMID - a pyramid with a triangular base and 3 triangular faces.\n\nSCALENE TRIANGLE - a triangle none of whose sides have equal length. The angles don't have the same measures, too.\n\nISOSCELES TRIANGLE - a triangle 2 of whose sides have equal measures. Therefore, the angles opposite the congruent sides have equal measures also.\n\nEQUILATERAL TRIANGLE - a triangle all of whose sides have equal measures. The angles have equal measures, too.\n\nRIGHT TRIANGLE - a triangle 1 of whose angles has a measure of 90 degrees. The other 2 angles have measures that are less than 90 degrees. The side opposite the 90-degree angle is the longest side and is called the hypotenuse. The other sides are called legs.\n\nSPHERE - is shaped like a ball (round).\n\nCONE - it is a pyramid with a circular base.\n\nDECAGON - a polygon with 10 sides.\n\nDODECAGON - a polygon with 12 sides.

According to the measure of the angles,triangles are of three types.These are\nAcute angled triangle,right-angled triangle and obtuse angled triangle\n\nAccoding to the measure of the lengths of the sides, angles may be of the following types Scalene triangle-In salene triangles,all the three sides of the triangle are different.\nisoceles triangle-in isoceles triangle ,two sides of the triangle are equal.\nEquilateral triangle-kWhen all the three sides of a triangle are equal to each other it is called an equilateral tiangle.

(1) Straight-sided shapes are called polygons \n\n(2) Others are classified according to the number of sides they have.\na) triangles ( three sides) \nb) quadrilaterals ( four sides) \nc) pentagons (five sides)\nd) hexagons (six sides),\ne) octagons (eight sides)

to indicate a solid shape wich has the same rectangular section on each planar parallele to its rectangular base.\nIt has two congruent rectangular faces and four lateral sides shaped as parallelograms (eventually rectangles)\n\nIf all the faces are rectangles, then it's called a parallelepiped
